I wore out a 1-8"tw 22-250 22" rock rock creek barrel with 33.5gr of r15 in win brass and 205m's. Velocity was 3250 with moly'd 75amaxs. It was a fun barrel.
Dont think I have ever seen win 22-250 brass that would take small rifle primers
My bad, 210m's.
Just scored 5k 205m's for 200$ so had that stuck in my head 😂
