Feed problem

[Mutt]

I had this same problem when I first built mine. It fed factory just fine be choked on my reloads. Turns out I was using a .... die with an rcbs shell holder. The RCBS shell holder was a little taller than the ...... shell holder. It wasn't allowing me to resize that last little bit of the case. When I went to load, they would stick and not let the bolt lock. I shaved down the shell holder and it fixed it. Now I am just using that same shell holder as the die.
