I'm shooting a 243AI with a 25" Hart 10 twist. I've tried lots of power and pill combinations and many shoot less than .5" 100yrd groups. My issue is that I've found a couple combinations that shoot 90g SCENARs .22" to .24" 5 shot groups @ 3080 to 3090fps. The best I've been able to get pushing 3200fps is .33". My question is: "is it better to give up some speed (120fps) for .1" more precision at 100yrds?
Since many of these loads were shot at different times and conditions, I plan on making a batch of the best shooting loads and try some 300yrd 10 shot groups in the same conditions to see if the groups hold together. Thoughts?
