So, I'm relatively new to the Lyman 310 tool. I currently have dies for .38 Special, .45 Colt, and .380 ACP. I've loaded 100 or so rounds of .45 colt without issue, and I have at least set up my .38 Special dies to my satisfaction. I'm afraid the .380 is kicking my butt. The biggest problem that I have right now is that the case expander doesn't do anything. I have the die screwed into the handles as far as it will go, and the expander is screwed into the die as far as IT will go, and it's still not flaring the cases at all. I even took the nut off of the expander to screw it in deeper. I'm not sure what to do now. Any suggestions?
