300 H&H flanged magnum from .375 H&H flanged magnum

Many years ago, acquired a lot of BELL brass in .375 basic from which I formed both .375 flanged and .300 flanged magnums. Now have 40 rounds of old BELL 375 flanged mangum formed brass and wish to form it into 300 flanged. The instructions for the basic 375 included using three form dies and neck reaming as well as trimming.

Key question, can I sensibly take any short cuts with the already formed 375 H&H cases? I have the form dies and neck reamer.

Regards, Tim

I've run 308 win cases down to 243 Win in one pass through a 243 die and then reamed them.


You might anneal them first to make them form easier.

The first thing to do is run the 375 case up in the 300 case, proceed from their with primer powder and a bullet..If that doesn't work use more vasaline!!
