Im joining this conversation a bit late so dont really expect any kind of reply, but heres my situation. We use this nifty bullet energy calculator when we chronograph projectiles. FPS calc. 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. There will be some variance, but we can work with that. BC. Or more. I know probably during your career youve only run into the type that would trade their lives for mine, but that by no means indicate the totality of the situation. Wad weight (gr) where v 0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. Best Overall Barrel Length for 5.56 NATO. Go back to the range or set your cell phone down and set up a target at a random distance300 yards900whatever. I find I get my best prone and offhand done at that distance. Crumpled ? 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 . 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. For example, if you double the velocity of a projectile, the muzzle energy doesnt just double, it quadruples. I actually dont like shooting past 500m these days. You want the specs of these two loads to match. Max Range: The furthest distance you want to be represented in your trajectory output. 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. For a better experience, please enable JavaScript in your browser before proceeding. Select a bullet from the list or enter in the properties below. . EDUCATION 101. Its easy to understand why we get so deep into the numbers. 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. The factual truth is that velocity & BC do matter. If you are chasing that last 25-50fps out of a given rifle/load at the expense of dangerous pressures, decreased brass life , and especially when that extra velocity might take you off the accuracy node of your barrel, then yes velocity doesnt matter. RL-19 for the 30-06 and IMR 4064 for the 308 no Varget I have been able to find around here. You already know that you have 3 mils to the dot. For me, they are at 5.1 mils low of a 100m zero at 500m. Youve clearly never had to point a real gun at a person like Ive had to judging by how eager you are to advocate harming law enforcement officials. Josh- Two things puzzle me. Use only your reticle, which should have real mils on it. \begin{aligned} &x = x_0 + v_xt \;\text{(constant v)} \\ &y = y_0 + \frac{1}{2}(v_{0y} + v_y)t \\ &v_y = v_{0y}-gt \\ &y = y_0 + v_{0y}t-\frac{1}{2}gt^2 \\ &v_y^2 = v_{0y}^2-2g(y-y_0)\end{aligned}, Georgia State University Hyperphysics: Trajectories, University of Utah Medical School: Firearms Tutorial, University of Alaska at Fairbanks: Projectile Motion.

Believe it or not, these are two very different things. Glad to see another 308-ophile! Copyright 2023/ Privacy Policy / Terms & Conditions. You literally cannot avoid it. Nope nope. Fpe - The bullet energy in foot-pounds at that distance. A private range . For an overall great rifle, there's nothing wrong with the most popular barrel length of 16 inches. The Pressure value used for each caliber happens to be the maximum SAAMI safe chamber pressure. Long range on the target line starts at 600m. We appreciate all of your support and use of our site. Posts: 6834. It's a ballistics calculator that's been designed to make comparing two bullets easier. window.dataLayer = window.dataLayer || []; Theres a reason that computer guided optics are becoming a thing these days. T/C Shockwave lists a ballistic coefficient of .240 for a 250 gr. Now, if I drop muzzle velocity to 2400fps that brings minimum expansion range all the way in to ~325 yds. Stopping power has plenty more factors than simple kinetic energy. Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, to more than 1,200 m/s (3,900 ft/s) in modern rifles with high-velocity cartridges such as . The load Ive found most accurate is 37.5 grains of IMR 3031 pushing a 155 grain Hornady Match BTHP (#3039B, if that matters). TOF - Time of flight (how long (in seconds) the bullet is in the air). The future and the technology in it isnt scary. And you can do it in only a few shots. I appreciate and use the JBM site regularly as well. While a good indicator of raw performance, it only gives the consumer a vague idea of how effective that ammunition will be. Watch where it impacts next to the target.

Muzzle energy is the energy of a bullet right when it leaves the firearms barrel. I was kidding. MOA is kind of a bitch system since there are various MOA versions. Great read, where in West Michigan is there a 500 meter range? I may try switching to H4350 where I was using H414. Stopping the attacker is far more important than killing him. 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. Few people completely understand the math necessary to calculate muzzle energy. The estimator uses a modified form of the Powley Ballistic Calculator. If you know the acceleration of the bullet, you can determine muzzle velocity from the kinematics equation. 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. Plug the acceleration, displacement and initial velocity into this equation: (Final Velocity)^2 = (Initial Velocity) ^2 + 2_(Acceleration)_(Displacement). Just to be a problem, Ill do 2300fps. Get the very best gear you can afford and make the most out of each shot. You wont need a chronograph or a dope card. Help me identify this beautiful flintlock rifle, please. the muzzle). + 1 inch at 50 yards, 0 at 100 yards, -5.2 at 150 yards, and -15.3 at 200 yards. 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. Facebook You need to pay attention to velocity in two aspects, and they are: So, as the title says, how does one go about figuring things out with only five shots? Close enough for what were doing. Based on the fact that there arenttoo many velocities that will get your given bullet from A to B and put them all in the same place, you are then able to do the last and most critical part of this whole process. Ive done similar work before with the JBM site. Ive been hunting with Hornady 168 HPBT match bullets for years and Ive never had an issue. Who are we? 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. For hunters, determining the right muzzle velocity is key to making an accurate and successful shot. 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. That load produces 2400fps from a 13.5 barrel. The UK legal limit for Rifles is 12 ft/lbs and for Pistols is 6 ft/lbs. Using holdover I was able to figure out to aim 11 inches high with a Ruger semi auto .44 mag @ 200 yards, talk about slow velocity, fire gun, 1 wecond silence and then whap. ; Find the square of the velocity of the firearm. With the first charge the muzzle velocities for the short and longer barrel were 1,095 fps and 1,231 fps. I consider long range in the field to be 500m and out. Man, we hear you, we hear u buddy velocity aint no important. I figure that is to much deviation if I have been careful reloading, 168gr bullet at 2400 fps? It is also the energy that the shooter absorbs through recoil by shooting. Tarkov Ballistics Calculator. Hold steady while we get the issue in our sights. I know what youre thinking. If you are a hunter, youve probably shot an animal that didnt drop in its tracks. 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.. To calculate the ballistic coefficient from range data, two velocity measurements and the distance between them are required. COOL STUFF : 25 ACP 32 ACP 327 Magnum 380 ACP 9mm Luger 357 . Effects of Barometeric Pressure, Temperature and Altitude. Then you drove down and check. Any bullet that even nicks a vital blood vessel will do the trick. Use the calculator below to calculate the kinetic energy of a bullet. Humidity can be simply set at 50 percent. Instagram If youve hit a deer, you can give him ample time to lay down and bleed, tracking a blood trail as necessary. Stop it. Ahh, the science of walking it in and then running calculations backward. 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. It looks like that first shot may have been down 4.5 mils. If you are shooting at 500m, make the lines 5cm apart. Its the same projectile, but the speed it travels greatly affects the energy it carries at impact. No wait. Semi-auto, (eg .308/7.62 for M1A)? Topped with full metal jacket projectiles, Winchesters training rounds plow through the target. Im loading 308 for AR-10 and 30-06 for a bolt. Theres no practical difference at all. Enjoyed your enthusiasm . 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). Ive found it to be very consistent. Okay, so now you have that. This article led me to looking into temperature sensitivity of powders. Now you know you have a bullet that impacts 5.1 mils low at 500m. This is just the sort of guy thatd buy an RV and then bitch about the cost of gas. If Im not mistaken, Travis Haley has shot the 300 BLK out to 1,000 yards. Pressure and temperature is different when the max ord is dozens of yards above sight line and this is assuming you are not shooting across a valley. 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. Dont believe me? This muzzle energy calculator should prove pretty useful in a wide variety of applications. To convert from ft/s to m/s, divide by 3.28. The calculator allows a range interval as small as . The idea is to provide realistic training rounds that deliver the same shooting experience as self-defense rounds. A well-placed shot with less than stellar ammo is more effective on animals, whether fur bearing or criminal, than a poorly placed shot with the best performing ammunition on the market. Go to the next section and enter atmospherics. You should carefully consider weight retention and projectile expansion or fragmentation as well. The standard equations of motion govern everything that moves, from bullets to butterflies. While deep penetration is great for reaching vital organs, too much penetration can cause the bullet to pass completely through the target, taking that energy with it. Many gun people will even use the term interchangeably with stopping power. But is muzzle energy important? What We Use Enter the first two variables, then press calculate. Pellet Weight: Grain. At best it should be considered a rule of thumb or an estimate. Contact Us. Its a game when its on paper for score, not life and death. Let your fellow shooters know share this article using the Facebook, Twitter and other social media icons below.
