Good stuff guys, B17 - true, which would be why an ammo company would label them for fast twist rifles, like +P ammo is so marked for said handguns.
No doubt folks here are more into "R&D" and that has always been more fun added during my lifetime of hunting. Trying out new things. Never hit a hair with an '06, though have a few with a Thutty Thutty.....from a 10" TC Contender. It out shot MANY rifles at the 100 yd line when I was in college
If need was the basis of what folks use, most NA hunters might be using a 30-30 or 30-06 with Bore-Locks......after all, they do work.
DD - may have to try that out.
