[QUOTE="willfrye027, post: 2655468, member: 114992"] With a 26in barrel: Necking up small primer lapua 6cm brass. Hornady and Norma brass gave similar speeds and Peterson pressured sooner. With h4350 my load was about 2830fps. Somewhere near 40.5 grains. Nice stable load there. Just worked up loads with same components but with n555 because it is a tad slower burning and I had some extra case capacity. That load is going 2940fps. If you had RL26 that supposedly gives the best speed but my summer time shooting temps are regularly 95+F so I am relegated to temp stable powders. [/QUOTE]
