gtag('config', 'UA-86427305-5'); A simple, easy to use muzzle energy calculator to find out foot pounds of energy of a projectile. The energy in Winchester Train rounds is sufficient to take down a threat in most defensive situations, the problem is where the energy goes. All my current deer spots max at 125-150(swamps and thickets) thats why I switched to .300 blackout exclusively. Fpe - The bullet energy in foot-pounds at that distance. It doesn't have any major disadvantages in velocity and is still overall quite maneuverable. You can have a super-fast load and have it be not-so-great. 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). Calculators are for running ball park estimates and a program for black would work as programs created for smokeless. So spend some time on the range and become proficient with your weapon of choice. That said, this article isnt about my rifle. 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. Wait. Bullet Properties. It is by no means a calculator, as it uses averages and gives ballpark figures. 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 . I will tell you that its not important. I printed it out just the same . As the bullet travels down the barrel, propellant gases build pressure and accelerate the forward motion of the projectile. Gravity pulls a .22 the same as it does a 338, so having put a value . 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. The benefits offered by a that kind of scopeare literally too many to list. Enjoy! This counter-intuitive property of motion rears its head repeatedly in projectile-motion problems. This will make the feel and point-of-aim comparable. Ive been on enough hunts to know it doesnt really matter in real life. 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. The best and easiest way to do this involves shooting at dirt and steel and then at cardboard. There isnt any shame in missing. When your rounds go trans-sonic (ie, from super-sonic to sub-sonic) on the way to the target, they can become upset and unstable, depending on bullet weight, form, etc. Thanks. Let your fellow shooters know share this article using the Facebook, Twitter and other social media icons below. The free recoil energy is the work that must be done to control the firearm upon firing. Because velocity has such a huge impact on muzzle energy, anything that affects velocity also affects energy exponentially. It can be accounted for by simple calculation in a mil/mil system. Unlike other chris, my eyes glazed over. Ill have to butt heads with this page over the course of several days to see what I can glean from it. Change barometric pressure or temperature and all that work is for naught. What Im about to say will bunch a lot of shorts in a lot of places. that would mean in almost 2 decades of hunting I would have passed on exactly one shot, but that extra 225 yards of effective range means I am not pushing the equipment right up to the edge of its limits when taking shots at any reasonable range I hunt at. Ive found that speed isnt key to accuracy at practical ranges. Weight. a gun image by timur1970 from Fotolia.com. 5865 S 77th Street The firearm generates a muzzle energy of approximately 130 ft lbs of energy at the muzzle whereas that of the air rifle is only about 26 ft lbs. It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. Nielsen Specialty Ammo makes custom slugs for airguns including Airforce Airguns, American Air Arms, Daystate, FX, Edgun and most brands of quality air rifles. This is the number placed into the ballistic computer as your muzzle velocity. 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. Once a baseline is established, you can alter it at will to match your conditions. Or more. 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. A decent scope that you learn thoroughly , I prefer a Quantum VX -2 4-1250 on my long range rifle . The email address you entered is not valid. In the case of a gun, the bullet replaces the piston in the cylinder . Zero Range. What Barriers Do To Ammunition Testing Data, The Best Self Defense Ammo Ballistic Testing. This calculator will display the foot pounds of energy, and help you compare the power of different loads. Register today and take advantage of membership benefits. If you know the acceleration of the bullet, you can determine muzzle velocity from the kinematics equation. Any bullet that even nicks a vital blood vessel will do the trick. Pure math, man. Gyroscopic stability Sg means the ability of a rotating object to resist the change of its rotating axis. I disregard any reading that is more than 10% out from what I would expect. Pressure isnt as critical as people think, either. Get out that barely-relevant copy of The Ultimate Sniper and hope that it holds the answers. Shooters in self-defense situations dont have this luxury. The links calculator said it would be 1079 fps, about 500 fps slower. Ive tested a variety of chronos and they are seldom fully accurate. Were at 5.6, so too slow. Actually look down your crosshair and see where the mil lines are. To convert from ft/s to m/s, divide by 3.28. Tape or glue a bunch of cardboard together and secure it to a bermsomehow. The bullet is whats true. Who are we? Granted you can shoot 20 rounds to walk that 13 308 into the target at a mile and hit all day long, but i found my 20 375CT with better BC and higher MV makes it much easier. Your 308 load moves approx 46 more at 1000 yards than my .260 load in a 10 mph wind. There is nothing to look at except for the last yard line. If youre shooting at 849 yards, .1 mil is equal to 8.49cm and so on. Skip down and change the units to mil in the first column and to centimeters @100m in the second one. Comments like this are why people dont like this community. Check shot one. Save my name, email, and website in this browser for the next time I comment. Watch for splash and impacts. Its at 4.6, so a half mil high. Muzzle energy isnt exactly precise or the most important aspect of ammunition performance. I would call this a reference more than a calculator. To calculate the ballistic coefficient from range data, two velocity measurements and the distance between them are required. Dont believe me? Tell your boss youre sick of your garbage gun show accessories and that you need a raise to get that US Optics glass. I push 2815 fps with a similar load to the one you mentioned out of my 26 308 (disclaimer on that in a second). If you'd like to learn more about each of the specific environmental factors, check out our list of frequently asked questions. But, if you refuse to acknowledge our 2A is put in there against tyranny, which exactly means when the gobbermint use goons in blue and green who do not know better to oppress the citizenry, i dunno what truth about guns you have to offer. The standard equations of motion govern everything that moves, from bullets to butterflies. Muzzle Energy will be rounded to the nearest whole number. Ive shot in competition, hunted successfully out to 500m+ and have never worried about it. However, death can take anywhere from 10 seconds to a full hour depending on how fast they bleed. 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. Bullet or shot weight (gr) 1 oz = 437.5 gr. Our calculator creates a proper ballistics trajectory chart that details range, drop, velocity, energy (fps), wind drift, and time. 6. 380 Auto +P: JHP: 90: 276: 1175: 380 Auto : Xtreme HPP: 70: 233: 1225: International Cartridge Corporation Ammunition Ballistics: Round Type Weight Muzzle . You literally cannot avoid it. Then enter the bullet weight of the bullet whose velocity you want to estimate. Play around with temps and such. Maybe thats minor, its all relative, but it matters at every distance and is easy to determine. Have you ever wanted to compare a fast lightweight bullet to a slower heavy bullet to see which one hits harder? It looks like that first shot may have been down 4.5 mils. I've found many "tables" to range from poor to worthless. CV = 1500 fps. Click Here to open in small window. grains. It allows you to estimate velocity based on your current zero and the amount of drop at another chosen range, say 300 yards. How to use the Range Calculator. What would YOU DO if an Airsoft Ref came up to you like this? So, real world performance can vary greatly. Muzzle energy is the amount of energy a bullet carries right out of the barrel. You get the drill. 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. 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. But bolt gun? Joined: Fri Nov 30, 2012 6:25 pm. 7. 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. Deer, pigs, and coyotes all drop just the same from 100m to 500m+. Youre good to go after checking range in meters, so press calculate. 300 Blackout, not just for sub-sonics. The UK legal limit for Rifles is 12 ft/lbs and for Pistols is 6 ft/lbs. Your point A is 100m, but your 500m point B isnt your expected 5.1. When talking about bullet kinetic energy, the word muzzle energy is often brought up. COPYRIGHT 2021, THETRUTHABOUTGUNS.COM. I dont trust chronographs but I do trust math. Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. Josh Wayner is a Michigan native, active competitor, Grand Valley State University alumni, troublemaker, and fiction author.
