I would use silencer shop. I believe their process is the fastest. It quietens my 308 down to a little less than a 22. Seems like I always read that good suppressor get it down to 130-135 with supersonic ammo.
Get ready to read a million opinions on which suppressor is best. Personally, I would get direct thread if this is for a hunting rifle. Quick disconnect mounts cost money, aren’t necessary, and add a decent amount of weight.
