Ive used a ton of the servicos primers.No issues in a 2011.Striker fired guns may have too light of primer strike.They run great thru a Dillon press and about 20 fps faster than federal in my gun
I’m running a BnA 2 stage with pivoting handle at about 10 oz total in mine.Has been perfect.Being able to adjust sear and trigger hanger makes it really nice.I also had a diamond 2 stage at similar weight without issue
I took almost .080 off the latch to get my nephews 6.5 prc to feed.It feeds perfect now.I didn’t have to use the aics tab arc sends with the action.The front of the mag stopped on the bottom metal in his chassis
