[QUOTE="freddiej, post: 2102378, member: 26227"] Caiati, Limiting to the 6.5 or 7MM family will make it hard for you because the only one I know that comes close is the 264 Win Mag (24" barrel). The only 7MM I know that would come close would be the same case but in 7MM (rem Mag in a 24"). the 139 grain slug has the potenetial for 3200 FPS with 73.9 grains of Mag Pro. now working with a few of the lessor known calibers.. say the 325 WSM out of a shorter barrel would be in the realm you are working in. 300 WSM could fit the bill with a 150 grain slug at 3300 FPS potential with H-414, Win 760, and H4350. My 270 WSM propels a 140 grain slug at 3160 with 63.1 of H-4831 SSC out of a 22" (average over the sky screens). Another 270 I have, 270 Winchester, puts a 140 grain slug over 2900 with H-4831SSC in a 18" barrel with Hybrid 100V and Win 760. Again average speed measured by chrono. I am told by a friend of mine in Texas that his 270 Win AI can put a 140 grain slug over the chrono at 3270-ish with 61.5 grains of H-4831SSC (24" barrel) [/QUOTE]
