It was brass you picked up and shot from others guns, and you have chambering issues then die is out of tolerances. What brand die? FL or neck sizer?
You should be able to only neck size and be able to chamber.
How does new factory ammo chamber? Have you taken your calibers and compared the measurements?
It is a combination of my gun and a buddies. I am reloading for him as well and we mixed the brass. Factory brass chambers fine, no problems at all. Before I got one stuck last night I produced 3 bullets that load great, but it took some work getting the brass to size. I am using an RCBS FL die.
