I can tell you that shooting semi vs bolt is night and day. I started shooting precision semi about two years ago and first year and i mean shooting every weekend year (not shooting twice in one year) i was very frustrated. I could go out and print 2" groups with my GAP 308 at 500 yards all day but not shoot worth shit with a precision semi. But with enough trigger time, and figuring out how to drive a semi rifle it can get close but will never be a bolt gun. However, the advantages of rapid engagement cant be beat and ammo capacity of a rifle without doing a reload is priceless. What i have found is that if you get good at shooting semis, it improves your bolt shooting even more. However, if you only shoot bolt and are great, it does not translate to shooting a semi.
