Was digging thru some old boxes yesterday and came across this article from an old Guns. Actual extensive tests of sporting rifles vs match rifles of the time.Winchester 52C and Rem 40x is included, both still benchmarks. Ammo is 2 target loads then Winchester Expert, that is a field load, think Blaser in a 50 pac. 100 yards, 10 shots,ctc. Statistically expect the 10 shot groups to be 1.24 times the size of 5 shot groups.
