[Unclenick]

The only ones I've got any experience with are .45 ACP that the magnet failed to catch on the way into a Dillon 1050 case feeder hopper. They reload, but the sizing effort is noticeably increased even in that big machine. If they go through twice or three times, they start to split. I haven't tried, but I don't think I would expect them to get through more than one reload cycle in a high power rifle, if I were going to try it at all. Perhaps others have some different experience and know better about them at that pressure level.
