I recently got a 24-47 from a private party. It will chamber very tapered jacketed military type bullets but won't work with any cast boolit. I have several moulds. I get rifling marks at approx. 3/16" from the case mouth and a jammed, stuck boolit left in the barrel. I am thinking of getting a throat reamer from Brownells to correct this issue. My cast work fine in two other mausers. I tried .325 and .323.
Any ideas?
