Quality consistent ammo that your rifle has already eaten well . It takes into effect things like atmospheric conditions, wind, and even allows you to make projections shooting both up and down hill. You can use those programs the same way. The .308 is good to a mile. Interval: Output solution distance i.e. Dont touch your elevation knob no matter what range youre shooting. So the differences for the 21/2 difference in barrel length were 136 fps, 144 fps and 153 fps . I guess I am going to be the guy that gets bunched up on your velocity/caliber claim. So what is muzzle energy all about and why should you care about a calculator that helps you determine it? For self-defense shooters, knowing the muzzle energy of your practice ammunition and your personal protection loads is important. The number I am using for the acceleration of gravity is 32.16 f.p.s. The heavier the bullet and the faster it moves, the higher its muzzle energy. Watch where it impacts next to the target. Save my name, email, and website in this browser for the next time I comment. For a game animal or a human attacker to die, there must be sufficient blood loss, usually through significant damage to the vascular system or a major blood-bearing organ. So, real world performance can vary greatly. Standard Metro conditions are: To calculate the free recoil energy of a firearm, the weight of the gun, the weight of the powder charge, the weight of the bullet or shot+wad and the muzzle velocity are required. Muzzle energy is often used to rate the lethality of certain loads. This calculator is a simple estimator. I like the consistency of the .308 myself, but it definitely peters out at long range. The second one isnt super critical, but just get it correct. Technically this is only true to a point. The cardboard should be about six feet high and three feet wide. Input the ballistic parameters of your bullet, shoot at chosen yardage, and measure the difference in drop in inches, minutes, or mrads, and hit a button. The 300 Blackout's .30 caliber bullet can be made especially long, and as the result may weigh up to 220 grains quadruple the weight of the typical 223 Rem round's. So heavy a bullet conveys a subsonic muzzle velocity and correspondingly softer report. What matters more is what the projectile does once it strikes the target. Align the 4 mil line with the center and observe where your impacts are. In addition, the muzzle velocity also affects the projectile's trajectory and terminal velocity. It all depends on what you consider long range to be. Note that these equations are independent of mass and do not take into account air resistance, a common qualification in simple physics calculations. How do I use the ballistics calculator? If you are using a screen reader or other assistive technology and are having problems using this website, or if you have any other difficulties accessing this website, What Im about to say will bunch a lot of shorts in a lot of places. Copyright 2023/ Privacy Policy / Terms & Conditions. You wont need a chronograph or a dope card. Different brands and batches of blackpowder will vary and that can't be put into the program because it won't be known. Thats not nothing. Great read, where in West Michigan is there a 500 meter range? For the record, the bullet is the 150 grain Federal Fusion. You literally cannot avoid it. So for existing firearms, longer barrels equal higher muzzle velocity and therefore increased muzzle energy. We can change that later. So, your practice shooting will be similar to what you will experience if you fire your weapon in a defensive situation. Ive been on enough hunts to know it doesnt really matter in real life. . Those were the CCI 40-grain Polymer Coated Clean-22 and the Eley 38-grain Subsonic Hollow Point . What youll need is ; EDUCATION 101.

A shooting chronograph is a tool that measures the speed at which your bullets leave the barrel of your gun. The heavier the bullet and the faster it moves, the higher its muzzle energy. To calculate muzzle energy, or Foot-Pounds Equivalent (FPE), you need to know the mass of the item being moved and the velocity it will be . The average is the calculated central number of a sample. Triple the mass triples the energy. Watch for splash and impacts. 3. Gun publications and avid shooters can run on endlessly about the energy of certain cartridges and even specific brands of cartridges. Mils are stoopid. Confirm your data using shorter shots. In order to determine the kinetic energy, you must know the velocity of the bullet and the weight of the bullet in grains. For an overall great rifle, there's nothing wrong with the most popular barrel length of 16 inches. I will tell you that its not important. Five hundred meters? For the record, my complete rifle is about $3000, which isnt much these days. An old black powder gunsmith in NC gave this to me 30 years ago: And after everything is done based on using information gathered in Zonie's post and you have gone to one of the Black powder loading manuals that has tables of velocity information for similar rifles, you. With the first charge the muzzle velocities for the short and longer barrel were 1,095 fps and 1,231 fps. COPYRIGHT 2021, THETRUTHABOUTGUNS.COM. This is a useful measurement in that you can use it to compare power settings of an airgun, the energy . 00:02 12:50. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. Exit out and be sure to accept your MV. The more complicated answer: Muzzle energy is the measure of kinetic energy a projectile carries when it . 2023 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved.

Spoiler alert: Rosebud is the sledand that book looks better on your coffee table, where it begs to be mentioned by college friends who knew you were in the military but didnt know you werent a sniper. HANDGUN BALLISTICS. The links calculator said it would be 1079 fps, about 500 fps slower. You make note of it, hold with the start of the duplex, so 3 mils, on the target center and fire a few more times. Shown in the table below are a few sample calculations of both Projectile Velocity and Barrel Pressure for the 9mm, .357 magnum, .44 magnum, .45 ACP, .223 / 5.56 NATO, .308 / 7.62 NATO, and .50 caliber BMG using CFR's derived method. Sighting (yards) Range Card. Good for you, bruh, because its party time. Can we really live without pissing off everyone else at the range while we set up a chronograph and force them all to hold fire so we can stand in front of the line? The UK legal limit for Rifles is 12 ft/lbs and for Pistols is 6 ft/lbs. Here goes: velocity isnt important. Go buy Magpuls Art of the Precision Rifle. where v0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. Blackhorn 209 posts 1,900 fps of muzzle velocity for 100 gr. I supposed someone could put the numbers in Excel and the program would "calculate" the #'s for you basically by just doing the math. ), FFP mil/mil scopes can be had for under $700 from SWFA and US Optics makes affordable scopes under $2000. Well Josh , Ill try to save you a lot of trouble here and it wont take a lot of charts and fancy $2,000.00 scopes and any math . Save that information. (And the former gets you much more street cred. This is the number placed into the ballistic computer as your muzzle velocity. It is by no means a calculator, as it uses averages and gives ballpark figures. Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. Copyright 2023 ShootersCalculator.comALL rights reserved. A low number indicates most numbers are close to the average. function gtag(){dataLayer.push(arguments);} Im joining this conversation a bit late so dont really expect any kind of reply, but heres my situation.

Yes, but you're going to need to get your wallet out. I figure that is to much deviation if I have been careful reloading, 168gr bullet at 2400 fps? It's not perfect but it will get you much better results than this simple calculator. Because the length of the barrel greatly affects both the velocity and energy generated at the muzzle, the figures touted by the manufacturer arent precise and certainly wont be specific to your particularly firearm. Use the calculator below to calculate the kinetic energy of a bullet. And Im trying to figure out how/whether the ballistics you generate are correct regardless (wrong MV, wrong bc, correct drops), which must be true since it works. Glad to see another 308-ophile! What would YOU DO if an Airsoft Ref came up to you like this? Use the calculator below to calculate the kinetic energy of a bullet. Go to the next section and enter atmospherics. Because we dont know it is 2400 yet, we enter 2500 first. Ballistic specifications for specific cartridges are based on measurements from tests performed using SAAMI specifications. Yes actually and Ill elaborate on how to figure that out in a minute . Just enter your bullet weight below and its velocity. Quick! Wind is different across the entire trajectorys height and range yet we can only eyeball the mirage and get one data point at the kestrel. We use this nifty bullet energy calculator when we chronograph projectiles. This calculator is a simple estimator. You're not currently signed in. Ralston, NE 68127 Gyroscopic stability Sg means the ability of a rotating object to resist the change of its rotating axis. The next step is to look for targets that are half the distance of your truing distance. There are many other variables that can affect the bullet . It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. Enter the first two variables, then press calculate. I consider long range in the field to be 500m and out. Get out that barely-relevant copy of The Ultimate Sniper and hope that it holds the answers. As detailed in other articles Ive written, most people never shoot beyond 300. That happens to be the longest distance at my local range. I like to shoot at steel for this part. Sure you want a hard-hitting round to ensure adequate energy transfer and penetration, but you also need to consider bullet design. The ballistic calculator will provide all the variables of your shot at a provided range. If you know the acceleration of the bullet, you can determine muzzle velocity from the kinematics equation. Impractical range begins at 1000. Continue reading if you want to understand what projectile motion is, get familiar with . Form factor = 0.719 Muzzle Velocity (ft/s) The best way to determine muzzle velocity is by using a chronograph. 5. Now that you know thats 3 mils, hold those 3 above the target and off to the side. Since we saw the impact at 4.5 or so, we hold the 4 mil line on your target center. Its far more complicated than high school math, even if that sometimes feels like the most complicated thing on planet Earth. But I can sorta verify bcs by measuring at the muzzle and downrange (Superchrono downrange) and calculating from those values. I printed it out just the same . You already know that you have 3 mils to the dot. Def.) v^2 = v_0^2 + 2ax v2 = v02 +2ax. Your browser's Javascript functionality is turned off. Josh- Two things puzzle me. Just enter bullet weight and velocity, and this handy foot pounds of energy calculator will return a muzzle energy value, in foot-pounds of energy. Doesnt this mean your method of attaining MV may yeild a wrong value for MV? This number can be used to get a rough idea of a rounds destructive potential. Yeah, this method is sort of a way to reverse-engineer your velocity. Once a baseline is established, you can alter it at will to match your conditions. Velocity (fps) 2214 2101 1991 1886 1785 1689 1598 1511 1430 1353 1283 Kinetic Energy (ft lb) 2721 2449 2201 1974 1768 1583 1416 1268 1135 1016 . Enter 100m as zero distance. Yes. . But do get that marker and a measuring tape or meter stick. Data entry. Causing immediate death with any firearm is difficult and there certainly needs to be an amount of luck on the shooters side, especially with the adrenaline and chaos that go with a dynamic situation. Although we dont always like it, a hunter can shoot an animal and let it run off a short distance to expire. More INSANE Airsoft Gameplay from my first time at Code Red. Chronographs can be had for around $100 and they definitely have their place. What should come first:consistency. Designed to expand, hollow points slow as they move through soft tissue, dumping energy into the target rather than passing straight through. It allows you to estimate velocity based on your current zero and the amount of drop at another chosen range, say 300 yards. Skip down and change the units to mil in the first column and to centimeters @100m in the second one. Muzzle energy isnt something that can be measured with radar guns or impact targets. If the mass m and muzzle velocity v of a bullet are known, its kinetic energy and momentum can be determined from the relationships Ek = (1/2)mv2 and momentum p = mv. Generally speaking, the longer the barrel, the greater the muzzle velocity (and thus the greater the muzzle energy) because there is more length for pressure to build before the air creates drag. Every fanboy seems to want to throw in humidity and Coriolis like theyre trying to impress someone, but it matters so little in real life at realistic ranges that its just safe to set it at 50 percent all the time. The average muzzle velocity of a .308 Winchester round is around 2750 fps (feet per second). It just isnt. Consistency builds confidence and confidence builds consistency. This muzzle energy calculator should prove pretty useful in a wide variety of applications. They perform the tests in a controlled laboratory environment. Interactive Escape from Tarkov ballistics calculator . Muzzle Velocity: Actual muzzle velocity corrected to the muzzle from the chronograph location. 7. Your point A is 100m, but your 500m point B isnt your expected 5.1. Assume 100 yard zero. But precision is not equal to accuracy. a) do your rounds go trans-sonic on the way to the target? Your information will never be shared and you can unsubscribe with one click at anytime. Winchesters Train and Defend line makes a perfect example. So what do us normal guys who dont try out fifty handloads in one sitting do? Ignore wind speed for this time. . The muzzle velocity of the CCI Stinger Ammo is 1,640 fps compared to the . I like the method for establishing drops as well, I dont always have access to a chronograph and this will likely be a valuable tool for me in the future. A ballistics calculator, primarily for round ball ammunition used in muzzleloading arms. I've found many "tables" to range from poor to worthless. It's a ballistics calculator that's been designed to make comparing two bullets easier. If you buy a Lyman reloading manual, youll see that they call out an accuracy load as well as a maximum load in their tables. 5 mils of drop. foot pounds . See the Resources for an online tool that allows for the input of very granular information about specific firearms and bullets to achieve estimates of muzzle velocity and other data related to ballistics. I never crimp bolt gun ammo. The calculated \(v_{new}\) should turn out to be 2,669. I may try switching to H4350 where I was using H414. A large target , painted flat white rigid cardboard or plywood , about 4 x 8 . Ive shot in competition, hunted successfully out to 500m+ and have never worried about it. It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. To calculate the muzzle velocity, a velocity measurement, the ballistic coefficient and the distance from the muzzle to the measurement point are required. . The idea is to provide realistic training rounds that deliver the same shooting experience as self-defense rounds. Muzzle Energy will be rounded to the nearest whole number. The folks at Precision Rifle Blog did a How much does it matter? series, and extrapolating their work from that, a 400fps advantage translates into a roughly 12% increase in hit probability (assuming identical conditions and shooter ability). Or more. If youre really careful, you can actually take that permanent marker and draw mils on your glass. You should carefully consider weight retention and projectile expansion or fragmentation as well. False. This whole concept just proves to me one thing . Most of you have missed more shots than youve made, except that one time you lucked out and actually hit that pop can that somebody else left on the target rail on the 300 yard line of your local range. I have been fortunate, for the two main loads I shoot in this rifle I have found good accuracy nodes on the higher end of velocities, but without having to run at max charges or push pressures. I select the Litz version of the Hornady 168 HPBT on the scroll menu. Just accounting for drop and firing. where v 0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. Any bullet that even nicks a vital blood vessel will do the trick. The guys at PRB are good, but they get real stale with their presentation and ideas on philosophy of use. Go back to the range or set your cell phone down and set up a target at a random distance300 yards900whatever. Range (yards) Range Velocity Damage Penetration Power Drop Time of Flight; 0 y: 0.00 fps: I HATE MATH !!!!!!! The real variable in long range shooting is wind, nothing helps you negate its effects better than a high BC bullet with good speed. Hold steady while we get the issue in our sights. Even if a cartridge generates 1000 foot pounds of energy, not all of that energy is used to push the target. If you havent picked up on it already,Im a mil man. Theres no practical difference at all. The velocity of a projectile plays an important role in the amount of kinetic energy it carries. x and y are horizontal and vertical displacement in meters (m), t is time in seconds (s), a is acceleration in m/s2, and g = the acceleration due to gravity on Earth, 9.81 m/s2. Ive always thought velocity had to be consistent to have decent accuracy, but my empirical evidence says this is not true. $$v_{new} = \sqrt{m_{known}v_{known}^2 \over m_{new}}$$. Ive been hunting with Hornady 168 HPBT match bullets for years and Ive never had an issue. In fact, math is in virtually every angle of shooting. Use your imagination. For my abilities and shooting the El-Cheap-o rifle I am, I think its excellent. Projectile motion definition. Muzzle Velocity Equation. Some police firearms are equipped to discharge bullets at over 1,500 ft/s. Set max as your actual max, so 500m for me. Keep it simple. Worry not, friend, I wont come out empty-handed. the muzzle). ProChromo, CEDM2, Magnetospeed, Superchrono (measures from sonic boom), and Labradar. And the expansion does more than slow the progress of the projectile, it also carves a wider wound channel than a comparable FMJ, creating more damage and more blood loss. Abstract. Few people completely understand the math necessary to calculate muzzle energy. Using the 80 grain load (basically is 1.5X caliber) I add 8.125 (FPS Factor) X 15 (barrel length over 24, up to 39) and subtract 5.75 (FPS factor) X 2 (2 inches over 40 barrel length) Starting book velocity of 1560 FPS plus 110 FPS = 1670 FPS. The 175 grain Eagle Eye loads I use do 2,620 out of my 20 LTR. This is the major problem with using FMJs for anything other than target shooting and recreational plinking. Youll discover that you will certainly want a temp-stable powder like Varget. However, for this to occur, the barrel would have to be impractically long. You may add items to the list on the right in order to create a bar graph comparing the different items. the figures were 1,187 fps and 1,331 fps. 2. *yikes* hope no one paid money for this advice. In fact, the faster an object is moving, the more kinetic energy it has. A private range . A lot can happen between the muzzle and target impact. Big deal right? The .308 doesnt peter out at long range. The equation used is: vnew = mknownv2 known mnew v n e w = m k n o w n v k n o w n 2 m n e w. Where the variables are as follows: vnew v n e w. the new bullet's velocity (what we want to compute) There you have it. Lemme give you one practical application for 1000+ shooting: killing govt goons when the 2A is finally applied into real use, which is why we own guns in the first place. Ahh, the science of walking it in and then running calculations backward. I have mine memorized at 300 , 500 and 800 yards and can do a 10 inch gong in 3 shots almost every time . Muzzle 25 50 75 100 125 150 175 200 225 250 Velocity (fps) 1900 1843 1787 1732 1679 1628 1579 1531 1484 1439 1395 Kinetic Energy (ft lb) 1723 . Bullet Library. I had not thought much about that before. inches. The calculation is done with the same program as the trajectory page above. All of these will lead to inaccuracy in the ballistics solution and the best way to compensate right off the bat is more velocity. Getting hard . Muzzle Velocity. The bullet hits next to the 2 line. Velocity is heavily determined by the length of the AR-15's barrel. Muzzle energy isnt exactly precise or the most important aspect of ammunition performance. Heres where it gets interesting. ; Multiply the resultant with the mass of the . lb Muzzle Velocity ft/sec. Our projectile motion calculator is a tool that helps you analyze parabolic projectile motion. You can calculate kinetic energy using the classic formula you memorized in Physics class. Max Range. Using the function: .

Bison Ballistics Munitions, LLC JavaScript is disabled. privacy policy. Ad & Review Requests Understanding and studying the kinetic energy of a bullet is important in determining terminal ballistic performance. Our Friends A page devoted entirely to traditionally styled .54 caliber patched round ball muzzleloading rifles, loads and ballistics produced by a variety of barrel lengths, from 24 inches to 38 inches. Math is irrefutable and forces you to accept facts. I shoot way too many different rifles and loads, so having a good bc and mv, when I can get them, might be quicker than even your method. The muzzle velocity algorithm uses the known barrel length, the time the projectile 410 travels down the barrel (event E), and the calculated ammunition powder burn rate to calculate a value for the projectile muzzle velocity. Next Post . If Im not mistaken, Travis Haley has shot the 300 BLK out to 1,000 yards. Drift - The horizontal drift from a cross wind. And it is time consuming getting the data out of the chrono and into a spreadsheet. Comments like this are why people dont like this community. Airgun Energy Calculator. Whether you need help solving quadratic equations, inspiration for the upcoming science fair or the latest update on a major storm, Sciencing is here to help. There will be some variance, but we can work with that. The benefits offered by a that kind of scopeare literally too many to list. Kevin Beck holds a bachelor's degree in physics with minors in math and chemistry from the University of Vermont. The calculator allows for plasticity of data across a full spectrum of environmental conditions. Those unknowns will make the outcome of the program into just a guess. Plus, Id never shoot an animal at that range and on targets it doesnt matter. I know twist generates drift at long range but 1) were talking drop, I thought, and 2) sure thought it was minor. Sight height certainly matters. No apologies, and youre welcome. . It is also the energy that the shooter absorbs through recoil by shooting. Deer, pigs, and coyotes all drop just the same from 100m to 500m+. Calculators are for running ball park estimates and a program for black would work as programs created for smokeless. Best Overall Barrel Length for 5.56 NATO. I have never seen one, probably too many variables. Use your new-found muzzle velocity to predict a trajectory to your target. Feet Per Second (FPS) I have five, all read differently by 100s of fps. Its the same projectile, but the speed it travels greatly affects the energy it carries at impact. by dellet Fri Oct 21, 2016 9:25 pm. After you make those shots, drive down and put markers or draw visible indicators over your bullet holes, which are certainly (or should be) directly under your target center. Thanks for the work . Good stuff Josh. I hear you F-Class guys and this isnt for you! Ive found it to be very consistent. Man, we hear you, we hear u buddy velocity aint no important. 1. Too fast. Excellent write-up. Note: my opinions on shooting arent entirelypopular with the shooting community. Our goal is to make science relevant and fun for everyone. Close enough for what were doing. This number can be used to get a rough idea of a round's destructive potential. So I am not only confused and perplexed by this, but am wondering just what it is Ive been attempting to understand all these years. To understand this, think about how hard a baseball would hit you when tossed by a four year-old versus its impact when pitched by Randy Johnson. I found this information on a 3X5 card in my notes. As gun people, we often become obsessed with ballistic data, particularly with energy and velocity. What about that .1? Go back and change that variable. Its at 4.6, so a half mil high. You will see the Kestrel calculate a new muzzle velocity.
