Regarding the title: what cartridge results from necking down the 8x57 to 7mm and trimming back to 57mm with no other changes? No, it isn't the standard 7x57mm Mauser, since the shoulder length and angle are different. And it has probably 5% greater capacity than the 7x57 Mauser, and perhaps 13% greater capacity than the 7mm-08.
Why is it that a guy asks a simple question and all he gets are questionable replies. Much like the simple question about annealing that was asked on here a few days ago.
Guys, all he is asking is what is the cartridge called. How [bleep] hard is that to understand? He's not saying that should be the next new wonder cartridge that we all can't live without.
