[QUOTE="ntsqd, post: 2170345, member: 93138"] So my Multi-variable Calculus class was the waste of time that I thought it was? Yea! Hated it! Big factor in crimping will be case length variance. Even a tiny difference in length will have a large effect. Next will be needing a positive stop of some type. Though other may differ, I don't think that "cam-over" is consistent enough. In various operations that I've set up to 'cam-over' in the past I could feel a difference from one case to the next. Used to be that Weatherby sourced his brass from Norma. I assume that this is still the case? If so, finding quality brass isn't the problem. Finding brass at all is the problem. I've long wondered about sourcing or making cases with a deliberately slightly thick neck, just so they could be turned to the nominal size (to fit & function a std. SAMMI chamber) and not be an interrupted cut. An interrupted cut would mean non-uniform thin spots in the neck. [/QUOTE]
