There is a lot to like about coated bullets vs traditional cast lead with lube. Health reasons--greatly reduced lead exposure. I'll be shooting Chey-Cast Coated bullets at the Bianchi Cup in two weeks. I shoot the .38 caliber 148 grain double ended wadcutter in a Production Model-14. The accuracy is outstanding and greatly reduced smoke which helps a lot when shooting the Bianchi Cup Barricade match which has very short time limits. Here is a link to the Chey-Cast website:
