DO NOT RELOAD THE UNIVERSAL SHELLS!!!!!! These have the light weight Aluminum like base and are considered non reloadable. You need the AA hulls for quality reloads. I' ll see if I can find the quote on line at the Hodgden site. If I can I' ll see if I can post a link. I have loaded a couple and they don' t load well and I believe are not safe d/t the base composition.
Couldn' t find it directly, but here is a good site to check out.
