I conservatively estimate that I have no more than a thousand rounds through it since I have had it new. Mostly my reloads, which are not as hot as commercial ammunition. Reloads I have fed it: 695gr Ball/215gr 5010 695gr Ball/210gr 5010 647gr Ball/220gr 5010
695gr Ball/215gr 5010
695gr Ball/210gr 5010
647gr Ball/220gr 5010
