I've been reloading for about three years. I only load 9mm and .45acp and use a Dillon 550C. Until recently, all of my experience has been with round nose projectiles. Recently, I switched to a truncated cone, coated bullet in both calibers. I check every round I load with a case gauge and so far, haven't had any issues with .45acp. But with 9mm, I'm having a hard time getting all rounds to fit the case gauge consistently. I've been working on this for a couple of months now and have learned that if the bullet isn't placed perfectly straight in the case mouth before seating, there's a good chance it won't fit the gauge. If the bullet isn't straight the case may bulge slightly. The amount of flare from the powder bushing has a lot to do with the bullet sitting straight. Too much flare and the bullet wants to flop around when placed in the case mouth. Too little flare and the coating may get damaged when the bullet is seated. I replaced the Dillon powder bushing with one from Uniquetek and it has helped a lot but not eliminated the problem. I've had discussions with a guy with the bullet supplier and he has been very helpful but doesn't understand why I'm having the problem to this degree. Apparently other customers don't have the struggles I have. I have thought about going back to round nose bullets but hate to give up on this. Also this bullet produces a very accurate round. I'm very frustrated and would appreciate any help with this.
