Just got some 100 grainers from Cheyenne casters here in states with this coating. Havent had a chance to try them out. Little pricy, just got a sample package of 50. will let you know as soon as I get a chance to try. Going to try in the .38 for time being. They do look like they came from a Lee mould. Roly's boolits might be better quality and consistency if they come from the Magna moulds.
