I expect it would. With the long neck, my rifle is somewhere in the middle. COL runs about 3.5", which definitely increases case capacity over the 3.34" cartridge.

Mine is topping out with the 250 grain bullet and IMR4350 at 2800 fps. One grain increments from 70-75 grains gives an extra 50 fps or so, quite a linear increase. But once I get to 75 grains, the increase with increasingly larger charges drops to 15-20 fps.

I have settled on the 225TSX and Ramshot Big Game however. 73 grains clocks 2950 with very consistent velocities at widely varying temperatures. Accuracy is outstanding.


Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!
