Has not been an issue yet...on only my second reloading however with most of it..have had an issue with the new stuff not wanting to chamber--about 1 or 2 out of 25 NEW Nosler brass...have talked to others with the same issue..not sure what is up with NOsler quality control..one would think for $50-$60 for a box of 25 this would not be an issue.. call me crazy..
