Tried shooting some of my first ever batch of home-cast boolitz- basic Lee t/l 158 gr. swc's -nuttin fancy. Some cases [maybe one outta 20]are swelled/bulged and wont chamber; all were resized. Guessing I started them into the case crooked, or I seated them too deep [all the bands seated below the case mouth.] I've heard leaving one band outside the case, crimping in the first groove, is better; I'll do that. Plan to load more this wknd., hope to avoid a repeat. Want to avoid overworking the brass, maybe I dont expand the case mouths enough. The bullets often dont wanna sit straight on the case as they're being raised into the seating die; I figure they'll straighten out in the die. Will they?
