Thanks for the advice Jeff. Yes, the 30% of case capacity caution is why I am not using hot pistol powders like some. The smallest charge I have loaded for testing is 30 grains. I'm pretty sure I will be able to go higher than that and still maintain subsonic velocities.
I have a 30-30 load using a 220 grain jacketed Hornady FPs that is that is whisper quiet. By whisper quiet, I mean the muzzle report is a "poof" and the bullet impact is a loud "thwack".Also, I purchased some Atomic brand subsonics for my suppressed 308 (175 grain Sierra Matchking) and they are whisper quiet as well. I'm hoping for the same with these 405 grain jacketed flat nose bullets.
Have you been able to find a 45-70 load that is "whisper quiet" when suppressed?
T.S.
