FW Conch your thought process does have merit and logic and I agree to some extent.

I'm sure a 6br (or its variants) would work better than what I'm after. a 6brx is actually what I had planned for my next build and I may still veer that way.

However some of us are just wired differently. lol My problem is I come up with a theory and want to persue the experimenting to test the theory. The way I look at it is. if it wasn't for wildcatter's we wouldn't have as many awesome cartridges as we do today.

I have a .223 "short" idea floating around upstairs as well. lol but that's for a entirely different purpose.
