![]() I have read some posts on other forums about this load, it will not cycle an AR, built to shoot on a bolt gun. There's no way around that with a subsonic bullet. But it's a cartridge designed for the AR to cycle, be accurate and be subsonic. There is another cartridge, basically a stolen version of the. 223 based cartridge that does this, it's called the. You'd need to use a powder slow enough, and enough of it to allow sufficient pressure at the gas port, and a bullet heavy enough to act as a cork, to again, allow the pressure. 223 be achieved that will cycle a 5.56 AR? Maybe if one could load a 150-200 grain bullet. I've experienced enough lodged bullets and they aren't fun.Ĭan a subsonic. Can one use light bullets in subsonic AR loadings? Probably, but I won't. In guns w/o a gas port I use lightweight bullets for subsonic. I know the 100 yard group was terrible because the bullet has destabilized. That was many years ago that I did that work and some of it is sharp and some is fuzzy. At 100 yards the bullets are keyholing and groups were around 4" if I remember correctly. It was a tackdriver out to 75 yards but with a rainbow trajectory. I think my subsonic AR load used Green Dot and i know it used a Sierra 70 gr. I also don't like using really fast powder. Of course with guns having a gas port near the muzzle, or entirely absent, that possibility is greatly reduced or eliminated. You also won't experience lodged bullets in the barrel. You'll hear it (or not hear it) when you go subsonic. I suggest that they start slightly higher, into the super sonic range and work down. Oh, and you had better know what you're doing. So to counteract this I tell folks to do exactly the opposite of what is suggested when loading. If too little velocity is attained or the bullet is too light the bullet doesn't exit the barrel and the pressure can be heard to FFZZZZZ as it leaks out the port. We're not dealing with much pressure when using fast powder in the 5.56/.223 when the bullet reaches the gas port. I like my subsonic loads to use a heavy bullet for the AR. The problem with subsonic loads in an AR is the gas port in the barrel. Sure it could be fired out of an SBR or handgun, but it'll never reach much above subsonic and be safe. I don't want baffle strikes, nor stuck rounds.Mark got it right, subsonic and not normal 5.56/.223 velocity. I don't plan to shoot subsonic much out of my rifle, but when the ATF lets me have my stamp, the giggle-factor is too much to pass up. The problem is, they all keyholed at 100yd.Īside from normal case prep, how important is enlarging the flash holes? I noticed some significant blow-by of the powder on the cases would fireformed cases work better? My powder selection of Titegroup, does not even come close to taking up significant volume, but I'm using a hodgson published load is this article outdated information? I did not lubricate my bullets, but I've got an old tumbler and some moly powder aka Old_Painless' method would this help with consistency? And finally, for those who have done it, what effective range should I measure my loads? I shot all 20 rounds at 100yd and amusingly enough they "grouped" rather well I was able to get respectable groups once I got my elevation holdover down. ![]() I have some specific questions regarding development of these loads for suppressor use (I'm aiming for no keyholing). These fired pretty well, but chrono'd all over the place:Ģ0 rounds: Av 1011fps, Spread 285, Min 828, Max 1113. 223 loads using Hodgson Published load data.ģ.1gr Hodgson Titegroup (I also have trailboss and Clays available) While eagerly awaiting my Specwar 7.62 to get out of jail, I took the time to create some subsonic.
