So I have a model 70 left handed 7mmWSM I want to rebarrel with a faster twist rate ! I'm also Having lots of trouble with finding quality 7mmWSM brass. Thinking about when rechambering trying to go to 300WSM brass . Have any of you guys done this ? Which has better quality brass availability the 300 or 270 WSM ? Is it worth fooling with or should I just go back to 7mmWSM Sammi spec and keep hunting for brass ? Thanks guys !
