I have been having an issue lately with 2 kinds of bullets getting stuck in my die. When I try to seat the bullet it will get stuck in the die and pulled out of the cartridge. The bullets will have marks around the top third where I believe they are getting stuck. I have adjusted my die and the screw at the top but still can not get them to consistently seat. I have had the problem with only plastic tipped bullets. Barnes TTSX and Nosler. Do you think it is a problem with my die, me or the bullets?
