![]() ![]() You can kill someone with it, but the stopping power is a whole other matter. 22 Short isn’t the best round for self-defense, it’s certainly better than nothing. 22 Short had a reputation for being able to take small game and control pests. With a very mild report, no recoil, and sufficient accuracy, the. 22 Short saw a great deal of use in shooting galleries, which were widespread from the late 19th century until the mid 20th century. 22 rimfire was the first American metallic cartridge. Developed in 1857 for the first Smith & Wesson revolver, the. 22 Short Ammo Sale From Various Ammo Retailers It may also require modifications to the firearm to prevent malfunctions and/or damage to the firearm.22 Short Ammo In Stock. It does require ball ammo rather than hollowpoint ammunition. Shooting a pistol underwater does not require subsonic ammunition-the speed of sound in water isn't the same as the speed of sound in air for one thing. Cleaning damage is another story altogether. Anyway, I don't believe I've ever heard of a rimfire barrel being worn out by shooting alone. The difference in a supersonic and subsonic rimfire round is not enough to result in a difference in barrel life. 22 rimfire, bolt-action rifle fitted with a modern suppressor and subsonic ammunition wins the contest with sound pressure levels (SPL’s) hovering around 110 dB depending on the ammunition. In the case of the former, you need sufficient speed to prevent the bullet from transitioning down past the speed of sound before reaching the target, in the latter, you start under the speed of sound to prevent the transition. I doubt that the effect is noticeable in a standard self-defense pistol, but if you're shooting long distance rifle or match rimfire, it's better to avoid the transition. The transition can bump the projectile around a bit. ![]() It's not necessary to be subsonic, supersonic works just as well-the key is not transitioning between supersonic and subsonic between the muzzle and the target. Staying on one side or the other of the speed of sound helps accuracy at the very precise level. In a rimfire, particularly a longer barreled rifle, there can be more of a noise difference as the "crack" is a larger part of the overall sound. Subsonic centerfire pistol ammo is not really noticeably quieter than standard ammunition, but the character of the sound may be identifiable due to the lack of the "crack". Features and Advantages a box of 100 rounds Long-range accuracy and effectiveness. Suppressors will deaden the sound of the muzzle blast but do nothing to stop the "crack" of a supersonic bullet. Subsonic centerfire ammo was originally designed to allow the more effective use of a suppressor. Loading for under 1100 fps didn't produce enough pressure to reliably work the action, so that idea was out also. Since that produced more leading than I cared for, I finally dropped the idea of using lead bullets for that load and went with FMJ. I finally just threw in the towel on trying to do it and went with a higher velocity (~ 1200 fps). It's been my experience handloading, that a 9mm 124 gr lead bullet is a real "pistol" (groan - bad pun) to work up a decent 1100 fps load for. Lighter bullets would have a more pronounced and less easily predictable drop due to the fact that lighter bullets have less mass, and that makes them shed more velocity at any given range than a heavier bullet that has more mass. Due to slow initial velocity, subsonic rounds have a more pronounced drop at any given range. The short answer to the "what range" is probably 50 yards max. Other factors are rate of twist, the actual air condition - "heavy" high humidity air has more of en effect than cool drier air. A truncated cone profile seems to work the best - hollow-based wadcutters seem pretty immune to the effect - and round nose lead seem to fare the worst. The profile of the bullet also has a lot of influence on how it behaves when going trans-sonic. Usually you can tighten up a group by either increasing the powder charge and bumping the velocity up a bit so it goes sonic in the muzzle and stays sonic the entire journey, or dropping the charge so all of the rounds stay subsonic. If you load near borderline with slow burning powder- say 1150/1175 fps or so, that's one of the causes of those pesky 25 yard "flyers". The worst case is having the bullet go supersonic just as it leaves the muzzle, then falling subsonic downrange. ![]() That eliminates the problem with the buffeting breaking the sound barrier causes as the bullet goes supersonic.ĭownrange, as the bullet goes subsonic, it gets jostled around again, but nowhere near as bad. Generally the bullet goes supersonic while it's still in the muzzle. Then you work up your load so that it either stays above sonic or below sonic from the muzzle to the target. (speaking of handguns other than a rimfire and handloads)Īhhh! That's where the rub & the fun comes in.įor best results you want to take an educated guess as to what your max range is going to be. ![]()
