Every once in a while, I 3D-print the primer catchers in a "different" color that I don't sell, simply because I had to use the left over plastic for something. So up for grab is a mint green primer catcher for the RCBS Rock Chucker IV/Supreme. It comes complete with the catcher, collector tube and ram slot filler.
The first one who wants it shall have it - respond here and send me your address via pm.
