Re: 7mm to stw
Bolt face is .540 (.532 to be more exact) on both I believe. The stw is off an 8m mag case if you want to check.
The barrel can be rechambered for sure. I load a 162 to 3.660 oal if you want to get
and idea of your mag well length. Go with a 26 inch barrel or longer. The stw really needs it to burn all it's
powder. With the heavier bullets it seems to suffer about 100 fps per inch or more under 26".
