I'm just curious as to just exactly how a barrel leads. It seems if you sized a Gas check to a bullet say .002 over groove diameter that the check would scrape all of the lead out and you would just have splatter on the muzzle but none in the rifling. Does the gas check actually jump over the stuck lead? or does the lead in ever so small melted amounts slip under the gas check ? It seems unless there was an awful lot of lead the next checked bullet would scrape it out. New Casting minds would like to know.
