Its a game when its on paper for score, not life and death. G1 Ballistic Coefficient Must be between 0.001 and 1.0. Range (yards) Range Velocity Damage Penetration Power Drop Time of Flight; 0 y: 0.00 fps: Here goes: velocity isnt important. Doesnt this mean your method of attaining MV may yeild a wrong value for MV? Tell your boss youre sick of your garbage gun show accessories and that you need a raise to get that US Optics glass. Few people completely understand the math necessary to calculate muzzle energy. Enter the actual temperature of the day. RIFLE BALLISTICS. If you havent picked up on it already,Im a mil man. Youtube, ABOUT US Yards - the distance from the muzzle. Notify me of follow-up comments by email. You want the specs of these two loads to match. And even when there is, the vast majority of cops and servicemen will stand with us, not some politician like king obama. Designed to expand, hollow points slow as they move through soft tissue, dumping energy into the target rather than passing straight through. Its about how uniform all your gear is. Muzzle Energy is useful in comparing cartridges, calculating recoil, and stopping power. Typical handguns have muzzle velocities in the range of 1,000 ft/s, which means that such a bullet would travel a mile in a little over five seconds if it hit nothing or did not fall to the ground by that point. Fire. 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. Consistency builds confidence and confidence builds consistency. Since we saw the impact at 4.5 or so, we hold the 4 mil line on your target center. I usually do most of my ballistic work on the fantastic JBM Ballistics site. Gyroscopic stability Sg means the ability of a rotating object to resist the change of its rotating axis. . And you can do it in only a few shots. Now, I'm not saying Lymans data is right but I've fired a lot of shots out of a .50 caliber TC using a 80 grain 2Fg powder load and they always "crack" when their shot. It's a ballistics calculator that's been designed to make comparing two bullets easier. A decent scope that you learn thoroughly , I prefer a Quantum VX -2 4-1250 on my long range rifle . Nope nope. Contact Us. . Just buy a chronograph, then you know for sure what your velocities are. Stopping the attacker is far more important than killing him. Line up and fire. 5865 S 77th Street Fire again twice. My best friend wears a badge and I used to wear chevrons. A shooting chronograph is a tool that measures the speed at which your bullets leave the barrel of your gun. Winchesters Train and Defend line makes a perfect example. Muzzle Velocity Equation. Lemme give you one practical application for 1000+ shooting: killing govt goons when the 2A is finally applied into real use, which is why we own guns in the first place. The best and easiest way to do this involves shooting at dirt and steel and then at cardboard. Go back to the line and look through your scope. The kinetic energy of the bullet is the energy that is transferred to the target when hit. To get to 300m, I need hold 2 mil below my 100m zero. No, not really. Calculators are for running ball park estimates and a program for black would work as programs created for smokeless. Is it actual MOA, like 1.06 at 100 yards or is it 1? So for existing firearms, longer barrels equal higher muzzle velocity and therefore increased muzzle energy. Start by entering your specific environmental factors and constraints as well as your ammunition and firearm details into the the calculator form. I may try switching to H4350 where I was using H414. 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). If you can stretch your memory back to high school science, you should remember that kinetic energy is the energy of motion. -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 The number I am using for the acceleration of gravity is 32.16 f.p.s. But I can sorta verify bcs by measuring at the muzzle and downrange (Superchrono downrange) and calculating from those values. Take the mystery and uncertainty of long-range shooting out of the equation with Impact! How do I use the ballistics calculator? Thanks for the work . 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. Plug the acceleration, displacement and initial velocity into this equation: (Final Velocity)^2 = (Initial Velocity) ^2 + 2_(Acceleration)_(Displacement). Multiply the product of the weight of the pellet (in grains) times the square of the velocity and divide that number by 450240. You literally cannot avoid it. Blackhorn 209 posts 1,900 fps of muzzle velocity for 100 gr. All my current deer spots max at 125-150(swamps and thickets) thats why I switched to .300 blackout exclusively. Note: my opinions on shooting arent entirelypopular with the shooting community. Id like to add a couple of things to what Josh said here: Mostly true. Neither does energy. False. No amount of calculation is completely accurate.

Click calculate, this will show you under Results 2 the aproximate Muzzle Velocity in FPS and Meters Per Second and Range in Feet and Meters for your Airsoft Gun. Wind is different across the entire trajectory . Examine the problem to find the displacement of the object and its initial velocity. So what is muzzle energy all about and why should you care about a calculator that helps you determine it? Theres a reason that computer guided optics are becoming a thing these days. Typically, manufacturers derive these numbers from data gathered using special ballistic test barrels. Inconsistent muzzle velocity results in vertical stringing. Theres no practical difference at all. Im a 30.06 guy , always will be , I collected way to much brass . The average muzzle velocity of a .308 Winchester round is around 2750 fps (feet per second). Put a night force on pops 94 youll plug hogs n yotes from a mile away just use that handy dandy ballistics calculator ignore the wind, it doesnt matter! For the record, the bullet is the 150 grain Federal Fusion. This is just about how I zeroed my McMillan .50. Sight height isnt that critical, unless you eat nails for breakfast and mount your ACOG on your carry handle. 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. Ad & Review Requests I have found variations in my crony similar to yours using both hand loaded and factory. Our projectile motion calculator is a tool that helps you analyze parabolic projectile motion. Go back and change that variable. Big deal right? Distance to Chronograph needs to be 0.0 since we arent using one. Pressure isnt as critical as people think, either. 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. Muzzle Velocity: Actual muzzle velocity corrected to the muzzle from the chronograph location. Thanks. This whole concept just proves to me one thing . Posts: 6834. Lets say it works out to be 3 mils at full magnification. Gun publications and avid shooters can run on endlessly about the energy of certain cartridges and even specific brands of cartridges. where v 0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. You cant avoid it. Chances are good that youve had to follow a blood trail before recovering game. 5.1 again, but the hard way. COOL STUFF : 25 ACP 32 ACP 327 Magnum 380 ACP 9mm Luger 357 . 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 . A large target , painted flat white rigid cardboard or plywood , about 4 x 8 . Calculate Muzzle Velocity from Instrumental Velocity. But bolt gun?

What matters more is what the projectile does once it strikes the target. The modifications permit estimates for less than nominal full loads and . Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. The heavier the bullet and the faster it moves, the higher its muzzle energy. Im about to save lots of TTAG readers the trouble of this labor intensive method of reverse engineering your velocity with a yardstick and a huge poster board. The email address you entered is not valid. Impractical range begins at 1000. The way I read the OP, he is asking if there is a program that will give velocities based on black powder loads. Max Range: The furthest distance you want to be represented in your trajectory output. 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. I find I get my best prone and offhand done at that distance. If youre really careful, you can actually take that permanent marker and draw mils on your glass. It is left set at the default of .5. Muzzle Energy Calculator. To use this tool, enter a bullet weight and velocity for a known load. So, your practice shooting will be similar to what you will experience if you fire your weapon in a defensive situation. It all depends on what you consider long range to be. 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. With the first charge the muzzle velocities for the short and longer barrel were 1,095 fps and 1,231 fps. Select your ammunition to prefill the following data attributes or enter your own values. FPS calc. There is nothing to look at except for the last yard line. If youve hit a deer, you can give him ample time to lay down and bleed, tracking a blood trail as necessary. Group size at 100 yards is just under half an inch in both directions (horizontal/vertical), so I say its half an inch. + .7 inches at 50 yards, 0 at 100 yards, -4 inches at 150, and -12.1 at 200. If thats only 300 yards, thats fine, but it wont be as precise as longer distances. I appreciate and use the JBM site regularly as well. This muzzle energy calculator should prove pretty useful in a wide variety of applications. Now that you know thats 3 mils, hold those 3 above the target and off to the side. lb Muzzle Velocity ft/sec. The Federal 115-grain 9mm ammo has a muzzle velocity of 1,180 fps, while the larger bullet is propelled at 1,000 fps. An old black powder gunsmith in NC gave this to me 30 years ago: And after everything is done based on using information gathered in Zonie's post and you have gone to one of the Black powder loading manuals that has tables of velocity information for similar rifles, you. We also collect information about your rifle scope so we can provide you with compensation results specific to your scope's make and model. Remember, it isnt about speed or barrel length.
