I had a similar issue with hornady brass in my 30.06. Only when I use a warm load of IMR 4064. If I use 4350, it's OK. The brass (Hornady only) has to be full length sized or it chambers hard.
It never happens with Rem or Fed.
I can only speculate that perhaps the brass is a little softer than other manufacturers.
I have no great love for Hornady brass anyway. Whenever I come across any, I make hunting rounds for my son. This way I know they won't be coming back....
