I'll be casting these over the next few days from the MiHec 45-270-SAA mould. These bullets will weigh between 285 & 290 grains depending on mix. BHN should be 12-13. You can have 300 sized .452 or .453 & lubed with LBT Blue for 15 cents each. As an example 300 shipped insured in a small flat rate box will be 52.75. Or if you would like them naked to size & lube yourself, 12 cents. I'll be happy to quote any amounts you like.
