![]() Reducing carrier weight, buffer weight, spring, increasing gas port size, adding a suppressor for more pressure, all of those things can help. A 100gr sub would give energy in the range of a 380 pistol round. Even then I'm sure it would be hit or miss depending on the gas system of the gun & gas port size. There are 1 or 2 companies I've seen that sell a 100gr+ subsonic that they claim will cycle an AR. You'll have no issue creating a sub load, cycling an AR is the major challenge here, if that's part of the goal. If you need to do pest control, it will be much more cost effective to just get a. Plus you can run very capable 125 or 150 grain supersonics in it. 300 BO exists and delivers something like three times the energy on target. And they already make 22LR subsonics.Īs others have said. It's a goal that even if you manage to accomplish, you end up with what basically amounts to a 22LR for energy. 223/5.56 AR that was essentially useless for doing anything but running subsonics. You'd basically need a lightened buffer, lighter spring, and a tuned gas system to generate enough back pressure to make the first point work. So not Titegroup or Bullseye and also not H110. Pistol powder yes, but something in the lil'gun or 2400 burn rate range that also doesn't mind being very low density. It would take a very short barrel, a suppressor, and an absolutely perfect balance of pressure and velocity to cycle. I am thoroughly convinced of a few things: The highest velocity at almost 1500 fps didn't even begin to cycle. In my 16" AR, the lowest I got to was 1055 fps. The ASP was designed for an operator to take out a sentry / guard usually head shot, or a light or dog without alerting the enemy.I tested it last weekend with AA#5 and 77 grain cast bullets. The user wanter the gun to function in semi or full auto mode so they would not be having to work the bolt on each individual shot. Because you have so little energy to work with the only way to make it more effective and function the gun was to make the bullet as heavy as possible. The ASP is certainly not a long range round as you are only 975 FPS at the muzzle. We use compressed Tungsten powder as our core material inside a copper jacket. 300 AAC Blackout bullet in Subsonic Handgun has built a world-class reputation for accuracy and stopping power. 308 Rex round was designed to be stable in a 1:10 twist and give expansion down below 750 feet per second. 20 thou thick copper jacket gives us the malleability to get down the barrel without creating wear. With high-quality cartridge cases and primers, Subsonic Ammunition offers the performance and accuracy shooters have come to expect from Hornady. Chasing hogs in West Texas, the Rex subs worked quite well at 125 yards and less. The tungsten core gives us the penetration through dense bone heavy clothing into a vital to take care of business.īecause of the low velocity it makes it very hard to impossible for the small bullet to fragment. But because of the Tungsten core we get really great penetration through clothing and soft tissue or bone. One good shot to the vitals with a 55-grain. When the weapon is shouldered and fired with a suppressor is on the gun you can actually hear the mechanics of the gun then the round impacting the target.įor the gun to function you MUST have a can on the gun. ![]() 22-caliber bullet is better than a gut shot with a 212-grain. However, before you start shopping for ammo, there are several other important factors you cannot overlook and be sure to check your local regulations to be certain that hunting deer with a. You will have to fire about 8 to 10 rounds through the barrel to coat it to help slow the bullet down. The coating does not cause any buildup as with molly nor can it be cleaned out. I like the Winchester 42 gr subs cycle well in my 10/22. The coating causes no adverse effect when switching back to hi vel ammo. I use winchester 42g subs in my 795, they go fine. CCI Subs and Eley match work really well through my CZ455. The rabbits, hares, and magpies really cannot tell the difference in price between the two makes. We have coated the barrels by shooting the ASP through the gun then we fired 4270 rounds through the gun in full auto fire. Then we put in a mag of ASP with the barrel hot the first round out the barrel was only 99o fps then 985 970 990. 223 100 grain ASP (Advanced Subsonic Product) round specifically designed for civilian AR-15 modern sporting home defense assault rifles with suppressors. So it takes 10 rounds to coat and then it will be subsonic from there on out. Extreme Shock Prez Jeff Mullins tells TTAG that the previous military-spec 127 grain ASP. 223 rounds didn’t work as well as one would hope. We do have a gel block shot with the ASP 5.56 filmed at 40k frames a sec that if Robert has a way to post it we will be more than happy to send it to him.
