I have had primers that were a bitch to remove after firing the Encore . The main difference in primers that I have observed insofar as extraction is concerned is in what the outside is made out of, if they have a copper base and rim they will swell and be difficult to remove and the extractor will jump past the primer- this is definately not a situation you want if you are hunting. The Winchester primer with an all steel construction is the one you want to go with, it doesn't swell and the extractor lift the primer easily the way that it should. I believe that the T/C Encore has the best trigger in the industry, these are fine rifles.
