Lake City Brass

[swpc629]

I am using Lake City brass for the first time. I am having a problem with the primer seating. The primers are binding and some will not even start to go into the primer pocket. What is the best way to get the primer pockets to where the primers will seat easier.

Lake city is federal brass for mil contracts and usually has crimped in primers. You need to ream or swage the crimp before primers will seat.
