I looked through the threads and couldn't find anything similar, so I hope someone has some experience with this. I have successfully loaded several 30 WCF rounds with the 160 FTX bullet. However, I went to load some more with brass that had been FL resized and when I went to seat the bullet it crushed the case. I thought that was very strange since it never happened to anything I've reloaded before. I grabbed another already FL resized case and a case that had not been resized and FL resized it and same result. It is like my RCBS die was not properly expanding the neck but I verified die set up. The bullet is BT so it had no issues starting but once it got to .308 width, it would not go in and then crush the case. Anyone have this happen and determined the cause?
