I shot well over 30,000 rounds. How do I know that?
I shot 6 sleeves of primers. Since a sleeve is 5000 to a box, that is 6 boxes that I went through. Mostly large pistol and large rifle.Now that I think of it, I went through 400 .50 BMG primers too.
As for the various guns of friends and students that I tried...I have no idea but its alot.
