I acquired a small quantity of Herters 44mag brass. I had a great deal of difficulty inserting primers, and I crushed more than one in the process. I cleaned out the primer pocket, and used a pocker "uniformer", but it made no difference. When I finally had them loaded, they would not cycle through my Ruger Super Blackhawk. Apparently the rims must be too thick, because every one of them would not rotate into position in front of the firing pin. (all other brands rotated without difficulty).
Did I get a bad lot, or are other shooters having the same problem?
