Some of my brass has a ridge while others don’t but I’m wondering if its from the sizing die. [The ones without the ridge might be a first loading.] My load is only 3.0 gr of Bullseye with 130 and 150 gr lead. I don’t think I’ve shot it enough to work the brass. Here’s what my cerrosafe cast looked like. It’s got an odd chamber, not a .310 or .32-20. The 32-20 shoulder blow out and you get a straight wall case. How long should the brass be?
