A while back I enquired on here regarding the 40sw and Win231 powder and an issue I was having with the FCD,and I haven't really reloaded any since that time. Not enough time to do everything that needs doing in life I guess. So I have managed to step into it again and I went back to that older thread and someone had mentioned that it's important that the crimp measure .0416-0.418. Given the issue I was having with the FCD I decided to crimp using the seating die and it seemed to be going ok until I revisited that thread and checked the current crimp. The boolits are not moving this time round and I thought the crimp looked ok but when I measured, the crimp was 0.425. The plunk test in my barrel works fine and drops freely in and out. What am I missing. Should I try to squeeze the crimp to 0.416-0.418?? Perhaps I had best check the calibration on my caliber today to be sure it's correct. Can't do it now cuz I'm at work.
