I was wondering if anyone has built a 416 Rigby or one of the big Wbys on a Rem 700 action and if so anything I should watch for? I will be using a seekings precision bottom metal and magazine, so I should have the COL taken care of in that area. I am using a custom bolt with a Sako extractor and proper head size. Anything else that I need to pay attention to? Advice would be appreciated.
