I recently piced up several die at an auction. One of the dies i cannot find any information on.
First, it is not a primer pocket swage die.
Second, it is stamped rcbs body 71 swage die p.p.
It is nothing like a pocket swager. It looks like a decapping die but the stem where the expander and decapper rod is different. It is threaded at the top like all others but where the expander and decapper usually go it is a straight smooth shaft.
Does anyone know what this die is for? Is the p.p. for paper patch?
Thanks, Lab
