Tim, when I've had problems with oversizing cases I don't find it's a problem with the dies. They're usually right but the rifle manufacturers do occasionally make some with a chamber on the long side of SAAMI specs. Then combine that with ammo that's on the short side and "click". It's a good way to find out if you flinch though. You may be right about the firing pin assembly. That's another likely candidate. I clean the insides of my bolt assembly and then use the Remington Dri-Lube. It won't sludge up the way that an oil will. Either that or run it dry.

I have just the opposite problem with my Bushmaster Predator AR15 it has a tight chamber and if I don't 100% full size I get stuck cases, I found this out after loading 100 rounds at about a 80% sizing, like I do for my bolt actions.

primers not seated tight or excessive FL sizing

I would say lube on primers if they hadn`t fired second time,,,could be a thin lot of primers also,,or some brass thats been overloaded,,I`d try it again with different bras and primes..

Likely. I'd also say firing pin dragging but it wasn't that cold this afternoon. Mr. big's probably right. I vote for oversizing. I like to have them where I can just feel a little pressure when closing the bolt so I know I don't have that little bit of headspace that can cause this problem. My namesake the 35 Whelen is notorious for this problem and I have to watch it like a hawk. My Ruger and NEF both have long chambers and you can't let the dies full length size and bottom out the press on the die or you'll get a nice click when you pull the trigger.

Take the firing pin out of the bolt and then try the brass to see what the fit is. It'll be a little safer that way. You'll still have the drag of the ejector spring but slowly adjust that die in until you can just close the bolt on a sized case. It's worked for me in the past. Good luck.
