I have an older 110 in 7MM and would like to use it for a long range build. I would like to convert it to 340 WBY. Other than the obvious changes(barrel, muzzle brake etc.) how do I obtain or change the magazine box (max COAL is 3.770)?
Your advice and expertise is greatly appreciated. Thanks in advance to everyone.
