Have learned a lot in the last 6 months or so that I've been reloading, but reloading 10mm has me frustrated. I've been using .401 coated cast from a few different companies. What happens is the oversized bullets buldge out the 10mm case too much. On recommendations, I tried using the Lee FCD but I have to run it the length of the bullet and it ends up swaging it down. If that would work, I probably wouldn't worry too much about the head of the bullet being slightly wider than anything post crimp. What ends up happening too many of the time is it'll actually swage the lead down and it just pushes out the bullet on the up motion. Just like squeezing out tootsie rolls. I'm then stuck with bullets too narrow to get a good crimp. Sometimes I can run the FCD twice and secure it but its not consistant and I feel like I'm just crushing these things.
What now? Should I just run .400 sized lead? FMJ? Do people not run oversized lead for 10mm? Any help would be appreciated. I havent run into any issues even close to this in any of my other calibers. Ugh!
