I'm trying to load some lead tcfp bullets for both a kahr cw40 and a conversion barrel for my glock 33. I'm having issues with chambering and OAL. The bullets are missouri 180gr and the data I'm seeing is OAL @1.125. At that OAL there is still a shoulder past the case and I cant get it to chamber in either gun. I pulled both barrels and they wont move freely. I changed crimp, I've used a bulge buster, I've used a factory crimp die and it's not the case. I can drop a case in and out freely. I started setting the bullet until I can get it to function and rotate and that's using an OAL of 1.100. Now I need help on whether I can use this OAL and if I can what powder charge should I use? I'm using bullseye and At 1.125 I see 4.2 to 4.5 gr. I have no idea where I should start. Any pointers would be great. I cant get it figured out and I'd like a safe starting point or direction to head in. By the way I've tried chey cast bullets with the same weight and shape and same issue. At first I thought it was just the bullet itself but it's not. Thanks for the help. Wanna kill these ads? We can help!
