Well, the day is starting out in a nasty fashion. My son is coming for a visit this weekend, wants to take his new Springfield XD 45 to the range so I started to load up a hundred shells. I'm using an old Pacific 3 die set and got the hundred resized with no trouble. Then I started with the second die which decaps and expands the case mouth. I used this same 3 die set last year with no problems. On attempting to decap and expand, only about half the cases would decap and when they did, the handle bound up on the up stroke. The ones that wouldn't decap, it was like the decapping pin was hitting to one side or the other of the flash hole. There are no marks inside the case at the flash hole. In either case, decap or not, the handle binds up at the bottom of the stroke and releases with a bang and the whole bench shakes. I thought about just going in to the shop and getting a new set of RCBS, but will run this by and see if anyone has any ideas. The press is a Lyman which has never given any problems.
