Welcome to the forum: if Iremember right my 378's had #3 barrels and the 30-378 probably has a #2 unless it is an accumark. Might be more practical to rebarrel.

Has anyone tried to redrill a .300-.378 accumark barrel to .378? Does the barrel have enough diameter to do this or will it require a whole new barrel? I'm considering building an African Accumark
