These are component bullets for modern or vintage rifles chambered for the .375 caliber cartridge. This is not loaded ammunition. These are newly manufactured soft point bullets (pure lead) with a 0.200" meplat (flat nose) that are perfect for tubular magazines of all lever action rifles. The ratio of copper to lead produces a well supported soft core with expansion controlled with jacket thickness, ogive, and meplat. These are excellent bullets that will keep any .375 shooting like it should. Also available without a crimp ring.
