Can you give it another .002 protrusion?

Possible excessive headspace. Easily checked by shooting loads that you do not resize.

Often it is difficult to see a broken firing pin without a new one to compare it too. Gunsmiths can spot a broken firing pin because they see them all the time. Most of the time when a firing pin breaks it's just the tip. The gun will fire sometimes with the broken firing pin.

I ran it out to .085 and no diff. I put it back to .065.

Had it out again today...5 rounds fire, one FTF and then one fired. Pretty annoying because I was seeing some results I liked.

I am temporarily out of ideas.

Damn. Well you replaced the spring, maybe try a new firing pin too?

Yeah, that's where I'm at too MM. I ordered a new one although I'm darned if I can see anything wrong with the one I have. Anyway, it'll either fix it or rule some things out.

I'll fix it one way or another. If I don't then I sure as heck am going to be drawn for antlered mulie next year and will be down in the coulees along the South Saskatchewan or the Red Deer River and there will be a giant mule deer buck struggling to walk uphill while pushing his humungous, wide, heavy 5-pt. antlers through the buckbrush and I will put the crosshairs on him and squeeze one off....."click".

Does the fire formed brass also fail to fire properly? Are you neck sizing or FL sizing? It could be a head space problem related to shoulder set back in the die? Does the fire formed brass maintain the proper case dimensions?

For the most part, I only neck size. I use Redding Deluxe (3 pce.) die sets almost exclusively. You've got me thinking, though.... I'll do some measuring, etc. tomorrow and post what I find.

I didn't even consider it could be a reload issue. Good call.

The fired cases are slightly larger in dia but that's to be expected. It's a .264 Win Mag so the resizing/shoulder push back isn't really a possibility, is it? It headspaces on the belt. I don't have headspace gauges.

I have noticed the firing pin strikes slightly off center. Could that bit of misalignment cause this somehow? If so, any idea how that could be fixed?
