I am using a Lee Loadmaster that I recently got, and while on my first attempt to reload I am finding at the end of the process some of the cases are mushroomed below the shoulders. I also find that after decap and resize some of the necks are rounded in so that a bullet cannot sit in it.
Any ideas on what is causing this problem? And please don't tell my to go buy a Dillon.
