I picked up some 52gr sierra matchking bullets a while back and figured I'll give them a go in some load testing before i transition to 75gr bullets. The grouping is better w/ 75gr and going to buck the wind a little better but only just.
52gr @ 3316fps, 1269 foot pounds (0.73" group)[std dev: 8.3]
75gr @ 2797fps, 1302 foot pounds (0.53" group) [std dev: 16.1]
currently using
55gr @ 2352fps, 675 foot pounds (0.83" group) [std dev: 66?!?]
The 55gr load is kinda crap but it good enough for 200y groundhog feeder. And is low enough pressure that its not abusive. Mainly though, everyone and their brother keeps 55gr in stock. fmj, sp, hp etc etc.
The question is....Which would be your recommendation and why? Targets include paper, gongs and groundhogs with ranges of 10-550yards. 90% of the targets will be under 350 yards.
