I have several Lee molds and all the pistol molds have worked fairly well with the 6 cavs working better than the 2 or 1 cav molds. The 4 or 5 Lee nose rider molds I have are under size on the nose from 2 to 6 thousands. I'm either the unluckiest guy in the world or Lee never made a nose rider that fits the bore. I don't expect a $20 mold to be perfect but .006 undersize on a nose is going to take more than a little work to fix. My 459 405 HB Lee casts between .453 and .457 depending on where you measure it and out of round by as much as .004. Why cant they get their rifle molds to cast proper sizes like their pistol molds? I guess making some more dies for the Swag-O-Matic to reshape and size the Lee boolits is probably the easiest. It sure worked for the Lee 458 405.
