Been reloading since I was 13, never used nickel plated brass, but now have some.
Might be a dumb question but...does the obvious difference in how it feels to the touch ("slicker" than s***) carry forward to when it is fired and result in less grip to chamber walls and more thrust to the bolt?
It's also more brittle.
Had a factory Winchester 7-08 cartridge split upon firing and got hot powder and gas to the face.
I'll take the brass made of brass, thanks.
