22 short barrel length subsonic3/10/2024 So the powder charge itself may be the same or more than a 40 grainer which is moving faster. But the answer is not neccesarily "slower is better", because a 60 grain bullet may be going slow but it still takes a lot of powder to get that big 60 grainer moving. But different powder types burn at different rates as well, and it is possible that some bullet designs change the way the pressure is released at exit. I had one chopped from 20' down to 16' and it improved it, although it was slightly louder which would account for the extra speed. A barrel longer than 16' actually begins to slow the bullet down again. Less powder charge is going to be the primary factor here. I believe 16' is the ultimate length to get best performance using subsonic ammunition. ![]() So, as long as your rounds are subsonic and you have a bolt buffer, the only area you can improve on is the barrel plosives. Bolt action rifles have very little of this besides the click of the firing pin as compared to a semi auto blowback like the 10/22. Action noise: The action cycling in a semi-auto. (if you use subsonics, you won't have this)ģ. Downrange sonic boom: the sound of the supersonic bullet tearing the air. This is the loudest source of noise unless you have a supressor.Ģ. Barrel Plosives (yes, that is a word): This is the hot gas escaping from the barrel as the bullet exits. All subsonic stuff is going to generate almost the exact same noise signature going down range.īasically, noise from a firearm comes from 3 sources:ġ. So with all of that above info, what barrel length should I buy for this short compact build. Lots of sanding.Click to expand.No, the only noise issue with speed is whether the bullet goes supersonic or not. I am needing to upsize the chase in the foregrip to allow for the compensator as my charger came OEM with a contoured barrel. Really dangerous with unutilized foregrip. I am installing linear compensator on those 3" as a guard to keep my fingers out of the path of bullets. Fired from a rifle-length barrel, this load approaches ear safe, with a sound suppressor, it produces no audible report at all. I can say the heavy barrel is much faster. Ive seen videos of some of the shorter barrels reaching out to 300yds but thats just a video and easily duped. Ive gotten mine down to a 2' group at 100yds at an indoor range. 22LR barrel length isnt going to make a difference with most shooters. SCYTHE-TI OMEGA 300 HYBRID 46 OMEGA 36M HYBRID 46M SAKER ASR SERIES CHIMERA 300 VELOS LBP SERIES SCO15 LOWER RECEIVER. the 4.5" barrel on my charger pistol leaves about 3" of foregrip without a barrel resting on it. 22 LR ammo being shot from various barrel length, I can see that the MV number are indeed noticeably less than the shorter rifle barrels. With the effective range youre going to get from a. Heres why we make barrel-length recommendations. The only concern would be the same concern I would have from any sudden barrel deflection while discharging the firearm.ġ. Shorter barrels are ideal if you want a concealable and easy-to-carry gun, while a longer barrel is the best choice for optimal accuracy. ![]() 300 Blackout depends on how you intend on using your gun. A non event in regards to mechanical safety. 300 Blackout Barrel Length: 9 to 10 Inches. 06 and if there was a sleeve strike it would really be mild rub and not a hard contact. 03 overbore so any barrel sleeve strike would be unlikely at an overbore of. My 4.5' AR will keep most Federal 36gr HP bulk pack ammo subsonic, but there are always a few shots that have a crack to them. The key to shorter barrels is the ability to keep HV ammo subsonic. Adding 12" is not going to be twice as bad as adding a suppressor and those often come with only. 2 CCI SV stays subsonic in a 16' barrel, so pretty much any barrel length will work for your needs. Regarding the barrel jump while firing: the projectile is traveling between 9 fps with one exception for the 90 rounds I tested from a similar 4.5" barrel from a charger pistol (that was not extended) with my bulk ammo. This is a contoured barrel so a bit more difficult but still sleeving a bit similar to a morse taper fit seems doable. Testing the Aguila 22 Sniper Subsonic 60 gr LRN ammunition in three different handguns into 10 Clear Ballistics with and without MDF bone simulation, as wel.
