Thread: Some new calibres for custom builds

Theres very little thats new in the wild cat world. Many decades of inventinve shooters and tinkerers have expolred most nooks and crannys in the brass shape department.New devlopments in powders and projectiles revive interest in things sometimes .The 6mm-204 is a 6x47 federal (not the 6x47 lapua) with a different head stamp and the 375 ruger has been pushed and pulled since it came onto the scene some years ago. The 7mm LRM as one maker is calling the 7mm-375 R with a few tweaks ) interested me a while ago, if it would clean up a 7 mm rem mag chamber then it would make a nice cheap alternitive in a T3 or simmilar, like the .338 sin can be a rechamber on a .338 winmag giving a good performance gain for little outlay. Greg have you pushed the shoulder back on your version to gain a little neck length? Nice to know theres a reamer in the country
