[QUOTE="Trnelson, post: 1567333, member: 42308"] I’ll have to assume that you are hoping to get the 140g class bullets to 3,000fps. The short answer is, I don’t think you would get there safely. 2,900fps, probably. Even with a 28” barrel there just isn’t enough case capacity in the Creedmoor case available, IMO. A 6.5/06 or a 6.5/284, (both of which have greater powder capacity) usually need a 26” barrel to get there. My 24” 6.5/06 tops out at 2,940 safely with H4831sc and shoots like hammered dog poo above 2,900. With a 24” barrel slower powders just take more powder to achieve similar velocity. Maybe one of the Sherman or Sherman short chamberings could achieve that. I’ll also watch to see if Rich chimes in. [/QUOTE]
