We had a thread not long ago concerning resizing new brass. I picked up some new Winchester 357 brass and started to load some deer getters. I loaded 12 and decided to go to the woods, but when I went to load my GP I had a couple of rounds that were really tight. I I went back to the bench to check it out. The tight rounds were caused by excessive case lengths. I checked several cases and found and much as .030 difference in length. Evidently I had set my crimping die on one of the short cases. When I crimped on the long brass it shoved the bullet in and put a slight bulge in the case causing the tight fit. A couple of cases were long enough to chamber tightly with no bullet. That could cause serious pressure on a hot load. So it might be a good idea to check your new brass for length. It might save you a lot of grief.
