What RgbyUser said.

Of what would be considered the more standard chamberings in the Pre 64, those in 375 (especially the Super Grades) are probably the most desirable, followed by the 300 H&H and that is reflected in their pricing. Check http://www.gunsinternational.com/ and search on 375 H&H and you will see what I mean.

If you have to chop it up

don't screw around with the action.
