[QUOTE="NeoConShooter, post: 1668768, member: 28881"] I would think that 140 grain bullets out of the Creed case which is slightly smaller than the 7-08 case would have less MV at any given pressure"? The MV listed in Wiki is 2,710 out of a 28" BBL at 62-63,100 PSI? IIRC Factory ammo for a 7-08 140 grain load is 2,810 FPS out of a 24" BBL? I wonder how the ability of the slightly higher BC of the .264 caliber 140 Grain bullet could make up the 100 or more FPS difference out of a shorter BBL over a similar tipped .284" bullet at +-500 yards? You see, I have a hard time believing it when people claim much higher MV from hand-loads that have not been pressure checked out of shorter BBLs than factory ammo that is already loaded to over 62K-PSI? Lastly, IIRC the feds think it takes a thousand foot pounds of energy to reliably take an elk. This puts a very real maximum range on smaller bore rifles that has nothing to do with trajectory! I'd like to know your thoughts on these questions. [/QUOTE]
