Home Forums Hunting & Shooting Gunsmithing 7mm SAUM or WSM on kimber 8400 magnum LA?

Hi there. I am changing my 338WM to something new and would like to know whether the 7 WSM or SAUM feeds better than the other? If they would not feed from the factory magazine I might go with CDI bottom metal. Have any one tried doing this on a long action 8400 magnum (with factory mag)?

Thanks

Pieter
