[QUOTE="Pdvdh, post: 2908587, member: 4191"] Your rifle chamber could be somewhat oversized in diameter relative to your resizing die. I suspect that condition would place some extra stress/strain on the case web, over multiple firing and resizing events. I think I had this large chamber / small resizing die experience, and experienced impending case web separations with a Ruger 77, chambered in 338 Winchester Magnum back in the late 1970s. Eventually ended up selling that rifle. It seemed I couldn't back the resizing die off the shell holder without difficult chambering of the cartridge. But that was many years ago, and I didn't have too much reloading experience at that time. There was no internet to learn from at that time. I did try to back my RCBS full length resizing die off the shell holder so as to only partially resize the necks. But that shoved the shoulders so far forward that I couldn't chamber the cartridges... It also could'a been a rookie mistake on my part. Not knowing what I was doing, and not having cartridge shoulder headspace measuring tools at that time. [/QUOTE]
