AH! Shit that is funny, i remember as kid, I would reload those red ring caps. used the red paper rolled caps, Cut the dark red center out of the paper cap with dads leather hole punch, then stuck it in the red plastic ring cap. were good for about 3-5 reloads till the plastic got to torn up. The red roll caps were fun, use to buy them by the 10000s, Was fun to hit the entire roll with a hammer also!
