Im guess your gonna use a pistol powder, from what I can tell from a picture of a pulled round...


Thanks.

Hi Accurate #2 loading guide has some sub. loads they use solo 1250 shot gun powder. My buddy loaded some did not like them in his bushmaster.
Hope this helps

Welcome aboard, PinTail!

Subsonics are tough. With a light bullet, the powder charge has to be miniscule. A heavier bullet is easier to slow down, but then they don't stabilize due to the reduced spin rate.

Then there's the expansion issue, which gets very iffy. Naturally, it's a very short range load, too.

Try a fluffy flake shotgun powder like Red or Green Dot. About 3.5 grains should do. And seat a bullet meant for the Hornet, one of the 40 or 45-gr softpoints with ultra-thin jackets. This isn't a load for a semi-auto, as it won't cycle.
