[QUOTE="MudRunner2005, post: 1527289, member: 12995"] Yes, but you run the risk of splitting necks running full-power loads while forming. This is why I always recommend running about 5-10% less than a book starting load. It might take the 2nd firing (at full pressures) for the shoulder to 100% form, but it will be 95% formed after the first firing (light load), the edges of the shoulders just might be not as sharp. My initial fire-forming gets me 95% there, and once they're formed the very next (2nd) loading is starting my load development. During this shooting process is where the shoulders sharpen up 100%. 3rd loading is once the load development is done, and they're all loaded to the same charge for shooting. [/QUOTE]
