Thanks for all the suggestions. I decided to take apart my dies and give them a good cleaning.

The case lube I am useing is water soluable and once I soak them in water I place the cases in the oven for a short period of time. I am guessing that my problem has something to do with when I am seating the bullet. I am trimming all my cases to length according to the Nosler reloading manual.

Get back to you later after I give your ideas a try. Thanks again.
