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 . Technically this is only true to a point. Wait. Abstract. A powerful .22 caliber air rifle such as a Benjamin Discovery or Marauder fires a 14.3 grain pellet with a muzzle velocity of approximately 900 ft/sec. Because we dont know it is 2400 yet, we enter 2500 first. 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. Muzzle energy is the amount of energy a bullet carries right out of the barrel. The free recoil energy is the work that must be done to control the firearm upon firing. I may try switching to H4350 where I was using H414. 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. bullet. A private range . 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. Yes actually and Ill elaborate on how to figure that out in a minute . I have a real-world rifle for real-world uses and it still does .1mil at 100m all the way to 1000m and Ive used it on animals and targets alike without issue. With the first charge the muzzle velocities for the short and longer barrel were 1,095 fps and 1,231 fps. Youtube, ABOUT US With the muzzle velocity calculation function, the bullet velocity V measured at a distance of x meters/yards can be converted to the bullet velocity V at the muzzle of the barrel (at 0 m/yds). For self-defense shooters, knowing the muzzle energy of your practice ammunition and your personal protection loads is important. Leave it. It just isnt. A low number indicates most numbers are close to the average. The way I read the OP, he is asking if there is a program that will give velocities based on black powder loads. Those centimeters are what you want. If you'd like to learn more about each of the specific environmental factors, check out our list of frequently asked questions. Enter the first two variables, then press calculate. Stopping power has plenty more factors than simple kinetic energy. So, your practice shooting will be similar to what you will experience if you fire your weapon in a defensive situation. 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. Enter the Energy (Joule) results from the FPS and Velocity calculator in the "Input 2" field along with your BB weight in grams. You may add items to the list on the right in order to create a bar graph comparing the different items. gave figures of 1,227 fps and 1,380 fps respectively. Bullet or shot weight (gr) 1 oz = 437.5 gr. So for existing firearms, longer barrels equal higher muzzle velocity and therefore increased muzzle energy. We use this nifty bullet energy calculator when we chronograph projectiles. You should always pick the load that gives you the best results. Next Post . Hold steady while we get the issue in our sights. -Muzzle Velocity (fps) 11 10 9 1/2 9 8 1/2 8 7 1/2 7 6 5 4 3 2 1 BB #4 Buck #3 Buck #1 Buck #0 Buck #00 Buck #000 Buck -Shot Size Steel Bismuth Tung-Iron Tung_Matx Chilled Pure Lead Heavi-Shot -Shot Type Mainly, you ignore bc. Getting hard . Josh- Two things puzzle me. It's a ballistics calculator that's been designed to make comparing two bullets easier. Good for you, bruh, because its party time. 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. just because it's impractical for hunting or target shooting is not a valid reason to dismiss the need for sufficient velocity. Here's how to do it. Remember, it isnt about speed or barrel length. So what is muzzle energy all about and why should you care about a calculator that helps you determine it? Pressure isnt as critical as people think, either. 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. Do not do that. I agree with your short&thick=rigidity=PRECISION. As always, its important to remember that at the end of the day there is no substitution for accuracy. Dont touch your elevation knob no matter what range youre shooting. Generally a good idea to avoid speaking in absolutes, on top of that, categorically stating that velocity doesnt matter is a bit misleading. Crumpled ? If you havent picked up on it already,Im a mil man. This is the major problem with using FMJs for anything other than target shooting and recreational plinking. Instagram If you arent shooting with a true first focal plane mil/mil scope right now, youre seriously handicapping yourself both at the range and in the field. Energy: FPE. Also, Microsoft Paint. Impractical range begins at 1000. ShootersCalculator.com is in the process of being massively overhauled. Removing margin of error is preferable to claiming superiority based on simplicity. On the other hand, Winchester Defend rounds are topped with jacketed hollow points. It is left set at the default of .5. Now, if I drop muzzle velocity to 2400fps that brings minimum expansion range all the way in to ~325 yds. ; Find the product of mass and velocity of the powder charge. We also collect information about your rifle scope so we can provide you with compensation results specific to your scope's make and model. Okay, so now you have that. (Thats 10cm at 1000m for those of you that measure in Freedom Units only.) With that bullet, at 2000 fps you will never be more than an inch low or high in a 100 yard shot. For a step-by-step guide on how to use the program, CLICK HERE! A $3000 scope and all that mumbo jumbo is easier than buying a $150 chronograph? That is why the concept behind the term stopping power is so important. 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). Muzzle energy is often used to rate the lethality of certain loads. What We Use Thats .1 mil at that distance, which makes 1 mil equal to 50cm. Take the mystery and uncertainty of long-range shooting out of the equation with Impact! For an overall great rifle, there's nothing wrong with the most popular barrel length of 16 inches. If youve paid attention, that is 5cm at 500m, also known as one click on a mil/mil scope with .1 clicks. Dont under estimate the importance of #7 . Continue reading if you want to understand what projectile motion is, get familiar with . All these fancy things are there to make that first shot and every shot better. Select a scope to prefill the following data attributes or enter your own values. 5865 S 77th Street I was kidding. 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. Any bullet that even nicks a vital blood vessel will do the trick. Range (yards) Range Velocity Damage Penetration Power Drop Time of Flight; 0 y: 0.00 fps: If youve hit a deer, you can give him ample time to lay down and bleed, tracking a blood trail as necessary. But do get that marker and a measuring tape or meter stick. Copyright 2023 ShootersCalculator.comALL rights reserved. Click Here to open in small window. Blackhorn 209 posts 1,900 fps of muzzle velocity for 100 gr. To calculate recoil energy: Obtain the momentum of the bullet by multiplying the mass and velocity of the projectile fired. A decent scope that you learn thoroughly , I prefer a Quantum VX -2 4-1250 on my long range rifle . Watch where it impacts next to the target. 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. Now line up and fire at the dirt in the berm next to it. Because we don't know it is 2400 yet, we enter 2500 first. Two of the loads were subsonic with muzzle velocity a little over 1000 feet per second. Round Ball Ballistics Calculator for Muzzleloaders, A trebuchet defended holler near Nameless, TN, Shot my first duplex loads yesterday in my .54-caliber flintlock. 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. Ive found that speed isnt key to accuracy at practical ranges. 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. 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. 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. So what do us normal guys who dont try out fifty handloads in one sitting do? If I was having a rifle built it would wear a 22 barrel, and experience shows I would still be carrying a nearly 300fps advantage over a 13.5 barrel. window.dataLayer = window.dataLayer || []; It all depends on what you consider long range to be. And have fun! How do I use the ballistics calculator? The .308 doesnt peter out at long range. In a self-defense situation, things tend to happen faster. Different brands and batches of blackpowder will vary and that can't be put into the program because it won't be known. I've found many "tables" to range from poor to worthless. BOOK VALUE for 2F, 24-inch barrel at 80 grains is 1560 FPS. This calculator will display the foot pounds of energy, and help you compare the power of different loads. Examine the problem to find the displacement of the object and its initial velocity.
