Subsonic 5.56

[Going Postal]

The Speer #14 manual has some subsonic load information in it. The loads call for AA5744 powder behind 55 grain (and lower) bullets. A friend asked me to load him some so he could check the noise level through his new suppressor. I load him about a dozen of them, he said they were quiet but would not cycle his AR. I don't know it that is a normal thing or not!

Yup thats normal. You can get a subsonic round but it won't have enough power to cycle the AR's action. As far as I know anyway

Buy some 90 gr bullets, get some Trail Boss, and get to loading.

A semi's not going to cycle, but that shouldn't be a surprise. And your twist rate probably won't stabilize the 90s.

I'm not sure what the point is though-- you've just created... .380 ACP, with poorer wounding characteristics, in a gun that's become a single-shot.

80gr projectiles and up will not fit in an AR mag. You have to single feed those.

I'm always looking for Trail Boss.

I reload subsonic 223. I use a 75gr bullet and a load I got off the internet. Works great. Wallacem in Ga
