RCBS Rock Chucker primer slot plug

thingiverse

Do spent primers like to escape out the front of your Rock Chucker ram when you're decapping? This plug will fix that. To install: 1. Raise the ram. 2. Slide the plug in from the front until it is sunk below the outer surface of the ram. 3. Lower the ram. 4. Use a dowel (or some other long piece of material) to gently tap the plug down. The bevel on the plug will slide it into place, flush with the surface. It's a pretty tight fit to the ram, so it may stay in place just from friction. If not, the plug has two recesses in it that will take 5mm x 2mm circular magnets.
