Re: 243 Vmax load help
I use the 87 VMAX almost exclusively for my AR10T .243 rifle. 43.0 of H4350 with a 210M primer. I've shot coyotes at 20 yards to 785 with similar results. I use the same load for antelope as well. The last time I shot paper, the group was in the .3-.4 range if I remember correctly. Speed is 3200fps. 1.5 grains higher is another node, but another 100fps and barrel wear to boot isn't worth it to me.
AR-10T in .308 & .243 both 24"
700 LA 7 WSM 30" 5R
AR-15 Rock River lower, WOA 26" varmint upper
Savage/ Broughton 23" .308
