I've been reloading 357 sig for a year or so now, and have just run into an issue. I recently picked up a S&W M&P compact in 357 sig, and started running my reloads through it. Now my first handgun will not chamber any brass that has been through the S&W. It's a XD 4". The brass will not set into the chamber far enough on the XD now to go into battery. Talking like .075-.1 out. The brass is under trim to length, and barely over minimum length, and the shoulders are in the right position as far as the numbers go. I'm at a loss on this one. Any ideas?
