[QUOTE="rpierce, post: 1964604, member: 20643"] Im guessing in my 26" barrel that powder charge would be around 3030 fps. The 30" barrel hasn't offered much more velocity than my 26" barrels. The 88.3 gr of n570 in my 30" barrel is 3095 fps and in my 26" barrel its 3035 fps. I realize theyre two different barrels also. Reloader 50 offers more case fill than reloader 33. Would be the same or slightly more speed. The case fill and speed is according to bergers info they put out. Retumbo, US869, H50BMG, and Reloader 50 all offered 100%+ case fill. N570 and Reloader 33 were 94 and 96% [/QUOTE]
