Trail boss didnt work so I might try 2205 cause it worked in the 300blkout

I've tried 2205 in 308 with 220gr RN's, and in 7.62x39 with 180gr RN's (bad bullet choice btw).

It works reasonably well. I got more consistent velocities than with trail boss. On the other hand, it's a lot slower burning than train boss - pressure is so low that cases don't seal the chamber, and there's more pressure at the muzzle meaning it's a fair bit louder.
