I found a set of 458 SOCOM dies cheap and bought em (admit it, you would too, $29) No Socom Yet but I'm hoping soon. Anyway, and this will prove how new I am, there are 4 dies, the instructions say "Lee 3 die set". (these were purchesd from Lee)

The instructions also say Load data on reverse side AND it's blank.



Anyway I think the first die is the decaping and resizing die, the second is the neck expander and powder charger, the third is the bullet seater, and the forth is??? I removed the collet for clarity only. I understand this PROVES what I don't know but I'll be better off next time I assure you. Thanks in advance

That's a "Factory Crimp" die. It is a better way to crimp than the seating die but get a hold of some adjusting instructions first. Lee will send or fax them to you.

458 SOCOM dies on sale at LEE'S surplus page. Looks like if you want some, better get 'em now ............ Captain
