Recently received a Mark V 300 Weatherby action from a friend. Was wondering if it is possible to use this action to build a 378 Weatherby. Was wondering if opening up the bolt face would be do-able and also if the 300 magazine would accommodate a 378 case or would there have to be modifications done. Guess I am just wondering if it is possible. | ||

short answer is no. the 378 is larger in diameter, and longer, won't fit mag or bolt. requires a rebarrel not rechamber, btw opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Design of magazine box and follower are different, but I would expect you could get correct ones from Weatherby. I would think any 'smith worth the name could handle the bolt face alteration. | |||

Weatherby will sell you the box and follower. Put a new barrel on and open the bolt face. Oh and a new extractor. Fairly easy to do. WOODY Everyone is allowed an opinion, even if its wrong. | |||
