RCBS Rock Chucker Supreme Primer Catcher

thingiverse

Primer Catcher for the Rock Chucker Supreme Press. I put several other models through their paces, but none of them met my expectations. This one was designed with a seamless fit in mind, requiring no tools or pins to install on your press. It accommodates even rough castings and should fit snugly around your press. Simply place the left side into the casting groove and drop the right side into position - it's that easy. I've used this catcher for over 1,000 rounds without any issues whatsoever. If you encounter a tight fit with your ram, take note of a small fillet at the bottom of the primer catch opening; gently sanding it down should resolve the problem. Fortunately, mine didn't require any adjustments. You'll need to provide your own 1/2" or 13mm tubing, which comes pre-assembled with a plug for the tube's bottom end.
