7mm WSM

What kind of speed are you guys getting with the 168-175 grain bullets?
 
0.96mm difference, right? Could that be fireformed out?
I think you'd have to neck up to 30, then down again to 7mm in order to create enough of a false shoulder to headspace on. So yes it can be done

Ah, fair point. Do-able but seems like a PITA.
Yeah, exactly. If starting from scratch on a build, a 7-300 WSM or 7-270 WSM are dimensionally the same as each other and established wildcats with reamers. You can use bushing dies for sizing. Although it would cost more up front, you'd save the difference in quality brass and time. I'd think that'd be the easier button.
