Decided to try my hand at doing some 308 subsonic. I'm using 180gr Sierra spitzer flat bottom. Loading that over 10.0-10.8gr of trail boss. No FCD used. I only chrono graphed 1 round for each. Groups at 35 yard really did not move much and tested those without the suppressor first. I did have 5 rounds of 10gr loads I made extra and took it to 50 yards and they shot pretty decent. I will make 20-30 more of the 10gr and try again. BTW they were wicket quiet. Target is at 50yds
