[QUOTE="Huntnful, post: 2776932, member: 116563"] It wasn’t the growth in the shoulder necessarily. It was in the case body at the datum line. It took a lot of pressure to force that area out to the walls. Sizing die wouldn’t even touch it after the first firing in my old chamber. This chamber could be different. I used 75gr. of N570 with a 225 ELDM in my old chamber. I could have just been very light on the first fire forming shot. But it also didn’t didn’t hold at the shoulder for fire forming. I had to Jam the bullet into the lands because the neck also shortened up. [/QUOTE]
