Any significant issues with converting an action originally built for a 300H&H to a standard mag cartridge, or a 375 H&H? I am thinking there should be no issues going to 375, perhaps some mods necessary for proper feeding going to a std mag cartridge.
Not worth bothering with. Here is a wonderful alternative>>>
Modified commercial Mauser from Herstal Belgium in 9,5x73mm... I don't see any oxidation spots on or adjacent to cross bolts, therefore, it looks like it is good to go. Excellent alternative to pre-64 .375H&H.
