For my heavy 260Rem I fireformed Lapua 243 brass. No issues with thick necks. And safe to say those 200 brass will last longer than the barrel.

That was before the Lapua 243 brass hit the market.


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!
