sounds good, with the massive amount of brass out there, it will be interested to see if it more efficient than a 300 stw?
Without exception, when you decrease case capacity without changing caliber or radically altering case design you end up with a more efficient case. When pushed to equal max pressures using the same components and barrel lengths, the STW will always outpace a 7-300WM by a fairly small margin. It just comes at the price of somewhat decreased barrel life and brass availability.
How about a 6mm-STW Improved?
a few years back i sat back to back, left/right handed at a long range match with a guy using one with a break....i had a set of inner ear the orangevalve kind, my muffs were stuffed full off those little orange squishy ones and then my muffs over top.... I've sat next to every cartridge know or at least used in matches and never heard anything like it before..it was the loudest and most miserable time i ever spent at any match, my ears rang for two years before it finally fadded, i have no idea how this guy could shoot this, i've hated the name 7mm/300 mag ever since..
