[QUOTE="parshal, post: 1316114, member: 605"] I've found the same thing but I do measure the shoulder bump. Sometimes it's not the shoulder making it difficult but the size of the case near the base. Measuring that spot with normal calipers is quite difficult. I'd suggest getting the Hornady comparator and measuring the shoulder to see if it's the should or the base causing the difficult bolt. My loads are all hot and I find it's the base that needs resizing after before the third reload. With a paper clip down in the case you can feel the thinning of the brass above the web. By the time you feel it, though, it's already too late. Case head separation is imminent. I speak from experience on that one having over annealed a batch a brass! [/QUOTE]
