The argument of not being able to find brass has been solved.Keep in mind the Sherman holds 2-3g more powder. I push the 181g Hammer at 3027 FPS and the 180 accubond at 3100 FPS. The Ackley version should get the 168 to 3100fps. If you go down this road buy Peterson 280AI brass and run it thru a 30cal expander. You will have way better results than standard 30-06 cases.I've used them for a 6mm Rem AI.

I prefer the 280 AI, as you get close to the same velocities as the 7mm rem but with much less recoil and better barrel life. Also it is my opinion that the 280 AI is MUCH less finicky than the 7mm rem. Better accuracy potential, better life, less recoil more than makes up for a few FPS the 7mm rem may offer.There are those who feel the 7mm Rem. is a bit overbore, and that the bore diameter is better served by the .280 Remington case, or perhaps the .280 Ackley Improved variant, but there are also thousands of hunters who sling a 7mm Rem.
