So many good powders to choose from. Not sure I would hold my hold my ground on RL15.
4831 looks good and I really wonder how IMR4166 would perform If no one else were tottery and share results w IMR4166 w the 70 grain projectiles I may never know. I am stuck on the 100 grain weight for my intended use.
agree. RL15 is a bit too fast for the 6mm Rem and 70gr bullets IMO. I got better results with powders in the RL17 - RL22 range of burn rate. Viht N160 gave very high velocity and great accuracy in mine with the 70gr TNT bullet.
