gtag('config', 'UA-86427305-5'); A simple, easy to use muzzle energy calculator to find out foot pounds of energy of a projectile. The number I am using for the acceleration of gravity is 32.16 f.p.s. That happens to be the longest distance at my local range. They are focused on PRS competition, which is fine, but there so few actual competitors in that that they may just write it up on Olympic biathlon. In just a few seconds, an attacker can carve you up like a Christmas ham and leave you bleeding in the street. I've found many "tables" to range from poor to worthless. Then enter the bullet weight of the bullet whose velocity you want to estimate. Something about lots of spectators makes my finger jump . You are good at drawing and drew an additional 4 mils on cardboard. The calculated \(v_{new}\) should turn out to be 2,669. I supposed someone could put the numbers in Excel and the program would "calculate" the #'s for you basically by just doing the math. Getting ones load standard deviation down into single digits of fps is challenging, but it can be done. Better put on your shades while reading this because your future is about to get bright. Here it is for those of us who have long since forgotten: To translate for the less mathematically inclined, kinetic energy equals one-half the mass of an object times the square of its velocity.. 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. I know people like you and you wouldnt last a minute against those you call goons. Anyways, go to jbmballistics.com and begin punching numbers. Muzzle velocity changes to an estimated amount of fps. How do I use the ballistics calculator? Ill tell you one thing . If you are shooting at 500m, make the lines 5cm apart. The average muzzle velocity of a .308 Winchester round is around 2750 fps (feet per second). 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. It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. Okay, so technically your gun now has two known zero points. It will a produce a line graph showing the bullet drop and flight path of the bullet. Some police firearms are equipped to discharge bullets at over 1,500 ft/s. You still dont know jack at the end of the procedure. The velocity of a projectile plays an important role in the amount of kinetic energy it carries. Make note of this. Stopping power has plenty more factors than simple kinetic energy. Im joining this conversation a bit late so dont really expect any kind of reply, but heres my situation. This calculator will display the foot pounds of energy, and help you compare the power of different loads. There are many other variables that can affect the bullet . Ive found that it is very rare for the hottest load of any cartridge to be also the most accurate. Formerly with ScienceBlogs.com and the editor of "Run Strong," he has written for Runner's World, Men's Fitness, Competitor, and a variety of other publications. 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. Well, one thing you can do is use our bullet comparator tool to see what the differences in ballistic performance is likely to be if you switch bullets. Never go full metric. Exit out and be sure to accept your MV. Even better. ALL RIGHTS RESERVED. The Recoil velocity of a gun calculator computes the velocity at which a gun will move in the opposite direction in relation to the projectile that it fired. A private range . Play around with temps and such. than trying to say simply if a bullet is stable or unstable. Now line up and fire at the dirt in the berm next to it. Effects of Barometeric Pressure, Temperature and Altitude. This calculator is a simple estimator. What Im about to say will bunch a lot of shorts in a lot of places. Were at 5.6, so too slow. For a better experience, please enable JavaScript in your browser before proceeding. Excellent write-up. As detailed in other articles Ive written, most people never shoot beyond 300. just because it's impractical for hunting or target shooting is not a valid reason to dismiss the need for sufficient velocity. (And the former gets you much more street cred. This is why velocity and energy generated at the muzzle will be the greatest over the course of the bullet travel path. Trajectory Calculation - Muzzle Velocity Without Chronograph. Semi-auto, (eg .308/7.62 for M1A)? The ballistic calculator will provide all the variables of your shot at a provided range. Unless youre in a competition like that, the 6XC and like calibers dont hold up against things like the .308 for real use on game. The calculation is done with the same program as the trajectory page above. I do 1.75. If thats only 300 yards, thats fine, but it wont be as precise as longer distances. Plus, Id never shoot an animal at that range and on targets it doesnt matter. Bullet Properties. The guys at PRB are good, but they get real stale with their presentation and ideas on philosophy of use. Then. e ( CD / BC / 8816) x CV = MV. Now you know you have a bullet that impacts 5.1 mils low at 500m. ShootersCalculator.com is in the process of being massively overhauled. Josh- Two things puzzle me. This will make the feel and point-of-aim comparable. ; Add both the resultants and divide them with the mass of the firearm in grams to get velocity of the firearm. Two of the loads were subsonic with muzzle velocity a little over 1000 feet per second. More INSANE Airsoft Gameplay from my first time at Code Red. 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. Its a game when its on paper for score, not life and death. The standard deviation (aka "SD") is a measurement that shows how much variation from the average number exists in a sample. Enjoy! Bison Ballistics Munitions, LLC At 2400fps, my bullet makes one hole at 100m and .1 mil accuracy out to 1000m. With 21 grs. Data entry. 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. (I saidfive shots is in the title, but you can shoot more if you want.) Breath deep , exhale , and walk em in and write em down . Although there are other factors that affect terminal ballistics such as the bullet shape and type, the kinetic energy of a bullet is useful for comparing different cartridges. Kestrel 5700 Ballistics Weather Meter with Hornady 4DOF. foot pounds . T/C Shockwave lists a ballistic coefficient of .240 for a 250 gr. Fire. My best friend wears a badge and I used to wear chevrons. Amer. You're not currently signed in. Sure you want a hard-hitting round to ensure adequate energy transfer and penetration, but you also need to consider bullet design. Sounds like a 30/30! 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, You cant avoid it. Thanks. Facebook This number can be used to get a rough idea of a round's destructive potential. Assume 100 yard zero. Data stays the same. Register today and take advantage of membership benefits. This is a useful measurement in that you can use it to compare power settings of an airgun, the energy . The UK legal limit for Rifles is 12 ft/lbs and for Pistols is 6 ft/lbs. Now that you know thats 3 mils, hold those 3 above the target and off to the side. Nielsen Specialty Ammo makes custom slugs for airguns including Airforce Airguns, American Air Arms, Daystate, FX, Edgun and most brands of quality air rifles. Fact is, my method works and offers the flexibility that modern people need when shooting for score or in the field. Ralston, NE 68127 Lyman found that barrel and load would give about 1573 fps muzzle velocity. This is something that is known as muzzle velocity, and it is a very important factor in determining which bullet cartridges will give their best performance at any given distance based on their weight and speed.. The load Ive found most accurate is 37.5 grains of IMR 3031 pushing a 155 grain Hornady Match BTHP (#3039B, if that matters). Sure enough, you have holes at 2.1 mils. You want the specs of these two loads to match. Copyright Ammotogo.com 2023 All Rights Reserved. The website will also let you include a zero at Point Blank Range, which is great for guys with the duplex reticles. You wont need a chronograph or a dope card. the muzzle). Examine the problem to find the displacement of the object and its initial velocity. Its about how uniform all your gear is. Definitions. trajectory information for 100, 150, 200 yds would be an interval of 50. Im shooting .308 Winchester out of a 26 inch barrel (but that is immaterial). That should even get you in the vital area of a Pudu. Diameter (inches) Weight (grains) Firearm. 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 shooting chronograph is a tool that measures the speed at which your bullets leave the barrel of your gun. They are by no means a traditional hunting bullets (the 185 is a tactical OTM whatever that means) but even Berger lists a suggested minimum velocity though, beyond that you are primarily relying on the bullet yawing to disrupt tissue which is proven time over to not be a consistent or reliable thing. We can change that later. However, that doesnt mean real science and math werent used to come up with these numbers. The more we all know, the better organized and stronger the shooting and hunting community will be. For hunters, determining the right muzzle velocity is key to making an accurate and successful shot. Form factor = 0.719 Muzzle Velocity (ft/s) 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? It doesn't have any major disadvantages in velocity and is still overall quite maneuverable. Bullet Library. Doesnt this mean your method of attaining MV may yeild a wrong value for MV? Converting an AR-15 to fire 300 Blackout is as simple as swapping its barrel. Thats .1 mil at that distance, which makes 1 mil equal to 50cm. The calculator allows for plasticity of data across a full spectrum of environmental conditions. Help me identify this beautiful flintlock rifle, please. So what do us normal guys who dont try out fifty handloads in one sitting do? At best it should be considered a rule of thumb or an estimate. Is there a calculator out there somewhere on the interseine for estimating black powder velocities? This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. What about that .1? It . Units of Measure . Your information will never be shared and you can unsubscribe with one click at anytime. It can find the time of flight, but also the components of velocity, the range of the projectile, and the maximum height of flight. Consistency builds confidence and confidence builds consistency. Our goal is to make science relevant and fun for everyone. I printed it out just the same . The .308 doesnt peter out at long range. You are trued - easy day! 1000 is an imaginary landmark 46 @1000 is nothing and easily accounted for. Once a baseline is established, you can alter it at will to match your conditions. Your 308 load moves approx 46 more at 1000 yards than my .260 load in a 10 mph wind. Remember, Targets4Free.com is your number one online source for 100% free targets, as well as resources like this one! 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. This is repeated in Winchester's Power Max cartridges. How fast a bullet is traveling when it leaves the end of a gun's barrel, called the muzzle velocity, is of great interest to both those who work in the field of ballistics and physics students looking to cover a few key concepts in one, well, shot. Also look at H-110. Close enough for what were doing. In a gun tube for firing rounds of smart ammunition, a sensor means applied to the ammunition which enables the calculation of muzzle velocity in the instant as the ammunition leaves the muzzle edge of the gun tube. The CVA Accura V2 Long Range muzzleloader is the top of the line model from CVA and has been rated the best long-range muzzleloader from Muzzle-Loaders.com. If your memory is a little off you may take a pencil and a notebook but leave your calculator at home . The ballistic performances for the 7mm-08 Remington based off a 24 inch test barrel on two grain types for muzzle velocity are 2,800 ft/s (140 gr Nosler P), 2,650 ft/s (150 gr Speer HC-SP). Youve just proven your immaturity to every sane person reading this. I actually dont like shooting past 500m these days. So the differences for the 21/2 difference in barrel length were 136 fps, 144 fps and 153 fps . That last number is a constant created by multiplying two times the acceleration of gravity by 7,000 - the number of grains in a pound. So lets just go forward with this example. The chart will provide you with the amount of compensation required to hit your target as well as the speed and energy of your projectile given a set of specified distances. Tell me thats not important. (Feet Per . I disregard any reading that is more than 10% out from what I would expect. Make sure its actually zeroed, because you will need it to be precise for the next part. I consider long range in the field to be 500m and out. The Train and the Defend ammunition produces the exact same muzzle energy and velocity. We appreciate all of your support and use of our site. What youll need is ; For the record, my complete rifle is about $3000, which isnt much these days. On the other hand, Winchester Defend rounds are topped with jacketed hollow points. I would like to shoot longer ranges, but I only have about 300 yards at the longest. Velocity - The velocity in fps at that distance. I dont know what the hell JBM stands for, but it works and is probably the best thing you can use next to the Applied Ballistics app or the ATRAG stuff. Muzzle Velocity. Thats how velocity affects muzzle energy. That carries ~400fps over your 13.5 configuration. As I learned at Pecos this year, a 10% difference in score is the difference between placing where Tyler placed (in the top 10) and where I placed (somewhere a good bit lower than top 10). Muzzle Velocity Equation. Yes. Using my pet load with a 165gr Nosler ballistic tip (min expansion @ ~1800fps) over 45grains of Varget (thats a full grain below max charge) pushed to 2815fps puts my maximum expansion threshold at 550yds or so. Save that information. All the ballistics from all manufacturers, finally in one place. How to use the Range Calculator. If youre shooting at 849 yards, .1 mil is equal to 8.49cm and so on. BOOK VALUE for 2F, 24-inch barrel at 80 grains is 1560 FPS. Diameter. One foot pound (sometimes written as ft-lb) translates to the amount of kinetic energy it takes to move a one-pound object one foot. This Airgun Energy Calculator is a simple widget designed to take the velocity of a projectile (bb, pellet, dart or bullet), its weight in grains, and calculate the foot pounds of energy (fpe) at the muzzle. I know what youre thinking. Theres no practical difference at all. 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. Your point A is 100m, but your 500m point B isnt your expected 5.1. Since my long range shooting primarily revolves around hunting, velocity also matters quite a bit where your bullet has a specific velocity threshold where it will expand and disrupt tissue as opposed to turning into a copper and lead ice pick, and your deer runs off to be eaten alive by coyotes. All these fancy things are there to make that first shot and every shot better. I never hunt with regular hunting bullets. For example, if you double the velocity of a projectile, the muzzle energy doesnt just double, it quadruples. Big deal right? So no matter how fast a bullet is fired, it is falling toward Earth just as quickly as if it had been simply dropped from your hand. . Just checked 1 difference on .204 32g .206bc @ 1000y is 9. Get out that barely-relevant copy of The Ultimate Sniper and hope that it holds the answers. Two measurements are required, the grain weight of the pellet you're using and the velocity from your Chronograph in feet per second (FPS) Enter Pellet Weight (Gr): Enter Velocity (fps): Power Output - ft/lbs Energy Expressed in Joules. Dissing long range just because its impractical for hunting or target shooting is not a valid reason to dismiss the need for sufficient velocity. Pure math, man. The sensor relies on measurement of magnetic field induced voltages which are unique as the ammunition leaves the muzzle . However, for this to occur, the barrel would have to be impractically long. Getting hard . Although shooters often argue over how much energy transfer actually matters, in a self defense situation that energy dump could be what stops a perpetrator. Topped with full metal jacket projectiles, Winchesters training rounds plow through the target. Befire anything you are a private citizen paying tax to keep the system alive, and your life and family are worth more than whatever uniform youre wearing. 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.
