[QUOTE="Okie4570, post: 3516838, member: 15643"] Just seeing this thread for the first time. I've been reloading for almost 40 years, but have only reloaded subsonic in the last couple years, and for only the .300Blackout out of a bolt action Remington. Some things that are different imo and something I had to get used to was that I was looking at max velocity and accuracy almost exclusively for subsonic and not max pressure. Pressure and reading my cases along with accuracy was what I always focused on with supersonic. I've reloaded subsonic loads with such little velocity and pressure with the .300blackout that the bullet didn't leave the barrel, and I could hear the gas escape when I opened the bolt lol. These were powder charges not far below the "max subsonic" recommended loads with some powders. Shooting thru a chrony every time when working up subsonic is necessary imo, both for subsonic noise purposes and safety. When you squeeze off a "zeroes" shot on the chrony, better double check your target and barrel and be ready to push your bullet out :) I've not tried to tackle the semiauto subsonic game where it needs to remain subsonic and still have enough pressure to work the action properly.
