I was pretty happy with the lee 500gr 3R non gas checked cast for subsonic in my bolt action and should be fun whenever it is that I get my suppressor. They were just at 50yds and have not had a chance to try them at any longer distance yet. Never actually used the strelok in the real world but it reads 6" drop at 100yds, 20.5 @ 150yds, 44" @ 200yds. Hopefully have some reports farther than 50yds in several weeks when I get to the range again.
