All of these calculators find the muzzle velocity at the shooting temperature by using linear interpolation given two muzzle velocities and two temperatures. Muzzle velocity changes to an estimated amount of fps. RIFLE BALLISTICS. You should say fk it and go buy one today. Humidity can be simply set at 50 percent. Hold steady while we get the issue in our sights. But I can sorta verify bcs by measuring at the muzzle and downrange (Superchrono downrange) and calculating from those values. just because it's impractical for hunting or target shooting is not a valid reason to dismiss the need for sufficient velocity. For guys who dont have first focal plane mil/mil scopes, the going is a bit tougher because you have no clear demarcations on your crosshairs and no ability to easily gather information. Combining complete onsite environmental measurements with the precise trajectory solutions of the integrated Hornady 4DOF ballistics solver, this rugged all-in-one handheld unit delivers the convenience you want and the accuracy you need for long-range success under any conditions. If you'd like to learn more about each of the specific environmental factors, check out our list of frequently asked questions. Ive always thought velocity had to be consistent to have decent accuracy, but my empirical evidence says this is not true. No amount of calculation is completely accurate. Firing under anything other than Standard Metro conditions changes the effective ballistic coefficient of the projectile (from Sierras 6th Ed). Or more. 4. Muzzle Energy is useful in comparing cartridges, calculating recoil, and stopping power. So, you have results. Just checked 1 difference on .204 32g .206bc @ 1000y is 9. Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. Play around with temps and such. 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. An important factor in any calculation of muzzle velocity is going to be the energy output - power - whatever you want to call it - of the powder you are using. Do not do that. Get out that barely-relevant copy of The Ultimate Sniper and hope that it holds the answers. The heavier rounds like 185 gr (12 g) Lapua Mega JSP will be lower at 2,510 fps, and the lighter 125 gr (8 g) Spitzer will be around 3100 fps. Because we don't know it is 2400 yet, we enter 2500 first. bullet. As always, its important to remember that at the end of the day there is no substitution for accuracy.

Interval: Output solution distance i.e. At best it should be considered a rule of thumb or an estimate. We thought you might enjoy it as well. 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. 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. It drops a bit at 1K+, but if you use your data, the hits come as regularly as with any caliber. 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. Its a game when its on paper for score, not life and death. 5. Use your new-found muzzle velocity to predict a trajectory to your target. Select a scope to prefill the following data attributes or enter your own values. I know people like you and you wouldnt last a minute against those you call goons. Just right. Triple the mass triples the energy. Thanks for the article. You're not currently signed in. The guys at PRB are good, but they get real stale with their presentation and ideas on philosophy of use. Here goes: velocity isnt important. ; Multiply the resultant with the mass of the . CV = 1500 fps. The modifications permit estimates for less than nominal full loads and . I appreciate and use the JBM site regularly as well. To calculate the ballistic coefficient from range data, two velocity measurements and the distance between them are required. Line up and fire. 300 Blackout, not just for sub-sonics. T/C Shockwave lists a ballistic coefficient of .240 for a 250 gr. Copyright 2009 | Ballistics101.com | All rights reserved. Units of Measure .

Pellet Weight: Grain. Here we specifically present the form these equations take in the case of projectile motion. Blackhorn 209 posts 1,900 fps of muzzle velocity for 100 gr. For example, if you double the velocity of a projectile, the muzzle energy doesnt just double, it quadruples. Please share, like, and tweet this page and others to show your support. Watch where it impacts next to the target. But precision is not equal to accuracy. I guess I am going to be the guy that gets bunched up on your velocity/caliber claim. 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. It is also the energy that the shooter absorbs through recoil by shooting. Muzzle velocity and energy are often stamped right on ammo packaging. Fpe - The bullet energy in foot-pounds at that distance. Its at 4.6, so a half mil high. Ad & Review Requests Make sure target angle is set at 90 degrees. The cardboard should be about six feet high and three feet wide. 4350 is good powder. I dont ever worry about expansion rates and such. Since the AR-15 rifle is such a highly customizable gun, there are various features you can change which impact muzzle velocity, and we'll examine them below. This calculator will display the foot pounds of energy, and help you compare the power of different loads. 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? BC. . Just accounting for drop and firing. The estimator uses a modified form of the Powley Ballistic Calculator. Muzzle energy is increased if you increase mass or velocity. I dont doubt you Josh , it just doesnt appeal to me and Ive been a reloader for 25 years . Drop - The vertical position of the ball, in inches, at that distance. Velocity - The velocity in fps at that distance. Aim small, miss small. Mils are stoopid. For a step-by-step guide on how to use the program, CLICK HERE! I've found many "tables" to range from poor to worthless. Keep it consistent and youre golden. lb Muzzle Velocity ft/sec. Sure you want a hard-hitting round to ensure adequate energy transfer and penetration, but you also need to consider bullet design. 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). 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. 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. Just buy a chronograph, then you know for sure what your velocities are. Ive found that speed isnt key to accuracy at practical ranges. 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. On your calculator, enter the following, being sure to enter the parentheses " ( )" characters in the equation.

Considering that a bullet from a Marine M40A5 is only seven grains heavier and a paltry 100fps faster coming out of a 24 barrel, Id say were doing just fine with the shorter barrel. By the way to prolong the service life of you brain by preventing overheating just buy MagnetoSpeed. 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. Even if a cartridge generates 1000 foot pounds of energy, not all of that energy is used to push the target. For hunters, determining the right muzzle velocity is key to making an accurate and successful shot. I agree with your short&thick=rigidity=PRECISION. There is nothing to look at except for the last yard line. Bullet or shot weight (gr) 1 oz = 437.5 gr. 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. Why waste 200 rounds when you can do it in just a few? Stopping power has plenty more factors than simple kinetic energy. 2400? Use the calculator below to calculate the kinetic energy of a bullet. Then enter the bullet weight of the bullet whose velocity you want to estimate. 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). I never crimp bolt gun ammo. There will be some variance, but we can work with that. 1000 is an imaginary landmark in rifle accuracy. Some police firearms are equipped to discharge bullets at over 1,500 ft/s. Muzzle Velocity (fps) Must be a number greater than 0. A $3000 scope and all that mumbo jumbo is easier than buying a $150 chronograph? Since Im struggling as it is to keep this whole yards and meters thing straight, Im just going to go full metric. a gun image by timur1970 from Fotolia.com. All projectile-motion problems are free-fall problems, because after an initial velocity is given to the projectile at time t = 0 of the problem, the only force acting on the projectile is gravity. Ive had access to literally any gun of my choice regardless of price over the years. However, the Train rounds would be a poor choice for loading your concealed carry weapon. Five hundred meters? In the case of a gun, the bullet replaces the piston in the cylinder . But why shoot a little gun like that when you could shoot another one? Doing this saves you having to goof around firing at every individual range. This system pairs range-ready Train rounds that are perfect for practice with Defend rounds engineered for terminal performance. Youre good to go after checking range in meters, so press calculate. Fact is, my method works and offers the flexibility that modern people need when shooting for score or in the field. Black Powder Shotguns Are Freaking Sweet! Its reactive and gives instant feedback. Even the factory loads that produce the best accuracy from this rifle are very inconsistent in their velocity and this really surprised me! You can have a super-fast load and have it be not-so-great. G1 Ballistic Coefficient Must be between 0.001 and 1.0. Now, if I drop muzzle velocity to 2400fps that brings minimum expansion range all the way in to ~325 yds. In order to determine the kinetic energy, you must know the velocity of the bullet and the weight of the bullet in grains. If thats a fast load, then good for you. What Barriers Do To Ammunition Testing Data, The Best Self Defense Ammo Ballistic Testing. Okay, so technically your gun now has two known zero points. foot pounds . The bullet hits next to the 2 line. . I have five, all read differently by 100s of fps. 1. Copyright Ammotogo.com 2023 All Rights Reserved. Yes you can. I love the long range stuff too .

You should carefully consider weight retention and projectile expansion or fragmentation as well. 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. To get to 300m, I need hold 2 mil below my 100m zero. 1000 is an imaginary landmark 46 @1000 is nothing and easily accounted for. I have never seen one, probably too many variables. Re: Muzzle velocity and barrel length. Free Ballistic Calculator. Fire again twice. (Thats 10cm at 1000m for those of you that measure in Freedom Units only.) FPS calc. BC = 0.300. It can be accounted for by simple calculation in a mil/mil system. Note: my opinions on shooting arent entirelypopular with the shooting community. Typically, manufacturers derive these numbers from data gathered using special ballistic test barrels. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. | 115gr | 1140 fps | 332 |, Thanks again for using our free muzzle energy calculator tool. Diameter. We can change that later. Enter a BC and matching drag function, or select a bullet from the library and then enter the following variables: Muzzle Velocity. Enjoyed your enthusiasm . Assume 100 yard zero. a) do your rounds go trans-sonic on the way to the target? (Notoriously enough, I do most of my shooting and hunting with a 13.5 .308.) 2023 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Converting an AR-15 to fire 300 Blackout is as simple as swapping its barrel. Sure enough, you have holes at 2.1 mils. 22 LR Muzzle Velocity: 22 long rifle muzzle velocity is the speed with which a bullet leaves the barrel measured in feet per second (FPS). For self-defense and hunting ammunition, muzzle energy is just part of the equation. That load produces 2400fps from a 13.5 barrel. 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. Its just uncomfortable for people who live in the past. Range (yards) Range Velocity Damage Penetration Power Drop Time of Flight; 0 y: 0.00 fps: To use the calculator, simply fill in the input values (blank white boxes) in the large black box. You should always pick the load that gives you the best results. The number I am using for the acceleration of gravity is 32.16 f.p.s. Its about building a range card based on data. Just curious how well youre .308 setup does at 800, 1000, 1200, etc. Use the calculator below to calculate the kinetic energy of a bullet. In just a few seconds, an attacker can carve you up like a Christmas ham and leave you bleeding in the street. The links calculator said it would be 1079 fps, about 500 fps slower.
