I'm getting a Glock bulge before I even shoot the cartridge as seen in 1st pic. One on left is a 165 grn Berrys and one on right is 200 grn WFNGC DT. Am I not putting enough bell on the case? These are AFTER being run through the Lee carbide Sizer/Crimper. I'm using a LW barrel and both fall in just fine, the Berrys 165 falls out on its own but the DT 200grn needs just a slight tug with the fingernails to free it. Using a dummy round with the DT 200 grn, the gun cycled it just fine. I have shot the Berrys 165 and they work great no hiccups at all. 2nd pic is of a belled case next to one that is not belled. (Sorry for the crappy pics). The case mouth on the belled one reads at .429", is this enough or do I need more? I don't know if this is relevant but both are at a COAL of 1.250". I appreciate your help.
