[QUOTE="RockZ, post: 306869, member: 5750"] Do you measure the headspace and compare the difference between rounds before and after being fired? And then after sizing to make sure you push the shoulder back a bit-.001-.002? The rounds that are hard to chamber may be your higher pressure rounds that have expanded the case more. Measure the case at the base at case head and see the difference. Try sizing the cases that are tough to chamber a bit more. Just turn the die down a little at a time , to push the shoulder back, and try to chamber a round each time until you feel just a slight amount of pressure. If it is difficult to close the bolt it needs to be sized again and the shoulder pushed back some more. [/QUOTE]
