I was just about to seat some charged cases and found a big problem.
My charged 357 starline case will not fit into the seating die.
I thought I went too far with the expander die, but that is not the case.
Lee seat die: .380
Flared starline case: .383
It actually started crimping the bullet (.35995) before I was half way seated. I'm surprised I only noticed it now. I loaded 50 with it 2 weeks ago and had terrible leading. I think it swaged my bullets.
Is this Lee die too tight? Can someone measure a RCBS or other for comparison?
Thanks,
Mick
