Another questions for everyone. I am having a 338-378 Weatherby built by a local smith. The issue we are running into is varying opinions on detachable mag options. I am going to be using a stiller tac 338 action for the build. Does anyone have first hand knowledge of the 338-378 Weatherby round fitting in the AICS CIP detachable magazine. The specs show it will handle the 3.750 COAL but was wondering if they actually work. Other options I have seen is the Badger Ordinance and CDI Precision Gunwerks. Any help would be appreciated.
