[QUOTE="Buano, post: 465129, member: 21641"] I don't know why your case necks split this soon. I can say from a metallurgical standpoint, the plating [U]should not [/U]have caused it. My thoughts go to the chamber dimensions on your rifle. If the throat is much larger than your cases there will be an inordinate amount of stretching & resizing, which would cause your cases to work-harden very quickly, & then cause you to need to anneal quite often. There is also a HUGE difference in hardness between brass from different vendors, and often between different lots of brass from the same vendor. If these cases have harder brass, they will require annealing much sooner & more often. Have you had the same experiences with unplated cases in that rifle? How much difference between the diameter of loaded case necks & just-fired empty case necks? If I still had access to a machine shop I would want to test the hardness of the brass in these plated cases & compare it to other cases. Perhaps someone on this list-serve will volunteer to test them for hardness. [/QUOTE]
