Also there’s the added benefit of increased ballistic performance. My standard load for the carbine now is Power Pistol @ 6.1gn with the RMR 115 fmj. Or, the shorter barrel’s bullet is equal to a hit at 275 yards from the 24-inch barrel. All information is provided "as is" with all faults without warranty of any kind, either express or implied. For top-end accuracy at the range, a longer barrel (and thus heavier) handgun will do the job better. A longer barrel gives you the opportunity to benefit more from a heavier grain. Thank you. A longer barrel gives you the opportunity to benefit more from a heavier grain. Muzzle velocity is the speed of the bullet as once it leaves the barrel. All the other revolvers we tested are fairly new. 9mm continues to gain in velocity up until 16” or so. I'm just trying to pick a length to shorten it to. However, the venerable .45 ACP is a different story. Interesting. data is provided purely for entertainment purposes - to better facilitate arguments The longer the barrel, the greater the velocity, and for self-defense rounds, higher velocities often translate to … The goal was to get at least 1500 fps velocity in my 16" carbine at standard 9mm pressure. Discussion in 'Handloading and Reloading' started by greyling22, Jul 11, 2018. My .45 is a Glock 21 which has a 4.6" barrel which probably not enough difference to note; while my SP101 is 2.25" tube. JHP: Cor Bon 125 gr. 9mm continues to gain in velocity up until 16” or so. Your choice. EDUCATION 101. To put that in perspective, you have lost the entire energy of a 9mm Luger bullet at point-blank. We did all the work. The barrel length itself is only part of the factor because a … Velocity and Barrel Length. Velocity; Energy; Average Range; Velocity in feet per second. were either familiar with, or because they were what was available, and mentioning JHP: Cor Bon 125 gr. Such loads still retain decent velocity even when fired from very short barrels. Hi-Shok JHP: Federal ... 9mm Luger; 9mm Ultra.357 Sig.357 Mag.40 S&W; 10mm.41 Mag.44 Special.44 Mag.45 ACP ('08).45 ACP ('15).45 Colt.45 … Although The High Road has attempted to provide accurate information on the forum, The High Road assumes no responsibility for the accuracy of the information. cylinder gap + 33.5 mm 1.32 in. And if you think you could do better, feel free to spend the money 1 decade ago. I compared velocities through the Scorpion (7.75" barrel) with those from an XD service model (4" barrel). 9mm Luger Results in fps. The sweet spot for 9mm seems to be around 15-16" barrel length. and in a 16" barrel it does 1160. do you think it would stay subsonic in an 7.75" barrel? Muzzle Velocity ft/sec. for a Muzzle Energy graph. The longest barrel I used was on the CZ Scorpion at 7.75” in length. 137.5 mm 5.41 in. This is an … 6 Creedmoor barrel length and velocity 6 Creedmoor is rapidly rising in popularity among long range shooters. 8” is kinda meh. No further tests will be conducted, but we will maintain this site and data for the use of I know different loads could change optimal barrel length but anyone have a ballpark? 9mm ammo barrel length vs velocity, 9mm ballistics vs barrel length, 9mm barrel length ballistics, 9mm barrel length velocity, 9mm barrel length vs velocity Combined barrel length and velocity results (note the data jumps from 16.5″ to 14″ in the tables shown below): Note the Black Hills 68-grain Heavy Match data shown below has an increased interval (2″) between data points for lengths 14 inches and below. This is anticipated since the cartridge was designed specifically for this barrel length. Pretty much any bullet at 147gr or heavier will be subsonic in a 9mm even with a 16" barrel unless you're loading 9mm major or using unsafe high pressure loads. Muzzle 25 Y 50 Y 75 Y 100 Y; 1180: 1106: 1048: 1001: 961: … +P variety will be zipping along around 1300-1350fps. The answer ranges from the precise, if wrong, "You lose 25/50/75 feet per second per inch" to the realistic "It depends on the caliber" to the resigned "I … The ballistics by the inch guy has a bunch of data. I know different loads could change optimal barrel length but anyone have a ballpark? Typically, a 9mm gun muzzle velocity ranges between 950 and 1150 fps depending on the bullet load and grain of the round. barrel length: Cor Bon 115 gr.
