I am loading 158gr lswc with bullseye. I am using many different brands of brass and am having problems with the bullets not going down into the cylinder of my revolver. I thought that it was a certain brand of brass that was doing it but its not. I loaded just Winchester brass and about half of the bullets would not fit down into the cylinder where the other half slid down perfect. Seemed like the tip of the brass had a larger diameter or does. I talked to a buddy at the range and he told me to take the punch out of the deprimmer die and run them up there a short ways. It works! However this takes a lot of time and was wondering if there is another way around it. Thanks
