I've got about 300 45 colt Oregon trail Lasercast. They are sized .452 and my rifle shoots best with .454. Was reading melting temps of silver and my pots won't get that hot. Was wondering if it was just silver solder. Is this possible to do in the Lee pot or just keep for handgun that shoots .452. Seems like a waste of a super hard bullet I could recast into my size 45 for the rifle or into a good hard cast for 45-70.
