I knew a guy who was really, really good at bump-shooting a semi-auto AK. Could empty a 30 round mag in a matter of a few seconds. I guarantee even he couldn’t come close, using drum mags, let alone 30s.
It’s a skill that isn’t worth much, really, but it’s great fun to watch!
I’d still like to see the one minute challenge. As long as I’m not paying for the ammo! (There were some real advantages to being in the military, at times.)
