[QUOTE="backwoods83, post: 588208, member: 29890"] I have found that RE22 is a good powder and RE25 is the best for the highest speeds and tighter groups but can be over 100fps temperature sensative. H870, Retumbo, H1000, and magnum are good for pretty high speed, great accuracy, and way less sensative with lower extreme spreads. I built a 257 roy on a savage 116 with a 28" barrel for a buddy of mine, it only has .270" freebore and it favors Imr4350 with 100s and H4831sc with 115s both with CCI BR2s. [/QUOTE]
