Just a word of caution with the old vintage herters powder. We were loading shotgun shells back in the70's and blew up two guns. a browning A-5 and a superposed before we were informed of a recal on the powder we were using . The first one we thought we made a mistake the second time we knew better . they replaced the one gun !! I dont remember the number on the powder . But I would proceed with caution !!!! Mark
