[QUOTE="Rhino55, post: 1665818, member: 40625"] [ATTACH=full]139924[/ATTACH] I have another thread going about a 260 IMP I built. Look for 260 Remington AI. I stand corrected on the "AI" because it is only 30 degree shoulders and JE Customs will jump on you for being not correct. I found my sweet spot is 43.5 gr under a 142 SMK.
