Did the misfire issue occur during fire forming 06 rounds into 06AI?
fireforming with factory ammo.
The neck on his chamber should be about 4 thousands short for a crush fit. So the case can't jump forward. Looks like bad primers, not firing in a different gun confirms its primers.
correct, you could see where the edge of the chamber hit the shoulder/neck of the case.

Ain’t the scientific method grand?
agreed, unfortunately we didn't have my old 06 out the first couple times.

Not sure why neither my buddy who owns it AND another 06 didn't think of it, but we didn't. The Hornady, and the first batch of Winchester both went untested in a different rifle.

here's a question, could a poor strike have damaged the primer to the point it wouldn't fire when hit with a good strike in another gun?

I’m sure there is a theoretical failure mode which the first pin strike could create, but it would be ridiculously rare. I would place my bets such you’d have two bad rifles before such a primer manipulation would occur. For example, the first rifle having a light pin strike but a fat pin, and the second rifle having a moderate/normal power spring but a short pin protrusion. A light but deep strike followed by a “hard but small and shallow strike.” Exceptionally low likelihood in either case - simplest answer when two guns go “click” is bad primer. When we hear hoof beats in the States, most often it’s horses, not zebras.
 
Maybe if the firing pin was way off center it could do something to the anvale in the primer. I would pull one apart as check the paper and compound. If the primer is not fully seated even striking the primer will not fire them, but most second try will fire.

Just enough slop between the factory ammo and the ackley chamber to push the cartridge forward when the pin hits the primer. That’s my theory

When fire forming my 6BR to BRA I had to jam the bullets into the lands to keep this from happening

The Ackley camber throat will hold the case headspace does not matter to much. The trim length being to short could cause problems, or if the barrel was not chambered properly.

messing up the chamber was my initial assumption, especially after that first box of Winchesters. Gauges checked out, and the reprimed/loaded brass fired.
I think I do still have a couple of the Winchester cases with the smacked primers in them. I'll look this afternoon.
 
I bet your chamber is fine.

If you were fire forming hand loads you’d have more control over the process. Off the shelf ammo, you get what you get, generally on the smaller size to accommodate every chamber on the planet.

Thats pretty much where my thoughts lay, but it seemed nearly as odd that Id manage to buy two different brands of rounds with bad primers. Unless something in shipping happened to effect them.

Either way it was a bit of a twisted little mystery.

I found two rounds of the last batch of winchester....ill take them apart after i get back from killing algae bags......
 
Took one of the two rounds apart, reprimed the case and pop. Primed another already fireformed case with the "bad" primer and dud.
The only thing I noticed the new Winchesters anvil was proud of the cup, could just be that.it hadn't gotten wacked a bunch of times yet lol.

Anyway, while my curiosity as to what happened to cause two different brands of ammo to have had bad primers isn't sated, I don't think I'll figgured it out lol.

Ive got a batch of new brass and bullets coming in. Usually id have done my own loads for fireforming, but when I sold my b14 to my buddy, i gave him all the 06 brass i had at the time.
I honestly was being lazy or id have ordered the stuff earlier. I wanted to take advantage of the Ackleys ability to fire standard rounds...my .280 does it wonderfully. Honestly I think those primers just caused some consternation, cause now that ive thought about I forgot to mention that those federal cases ive got came from my buddies stash of factory 06 rounds.
 
How many rounds of the ammo do you have left. Did you see what the gain in volume was ackleying it, can't remember if you did or not.
Ive burned up all the loaded ammo Ive got. I forget what the difference in water capacity was, but ill go grab my paper work on it in a bit. It wasnt a huge gain, but i can comfortably fit something like 65gr of rl-25 into the case with the drop tube i made, so it maybe enough to go to one step slower a powder. If not 62+ rl-23 here i come.

The info i scribbled down was for mixed cases, and all in the AI form.
I went digging to see if i could find any loos regular 06 cases and I found one hornady case that was still primed
empty 190.1
full 259.5
water 69.4

Hornady fireformed to 06AI
empty 191.6
full 264.7
water 73.1

So not much of an increase, were talking 5% or so. In fact Nosler lists the same max charge for rl-22 for both the AI and the regular 06.
 
Nother little update.....

Found what may have been the over ridding problem, ontop of some bad primers.

The knob thingy on the cocking piece was catching on the edge of the bolts cam surface at the end of the groove. I only noticed it after unpainted the bolt body, and the cocking piece scratched off the paint over a noticeable (once I was looking) flat spot.
I wasn't notielceable when dropping the striker manually, as the knob followed the contour of the cam surface and lifted over the edge at the end of travel.
When inside the gun it wasn't visible, and didn't hang up enough, or did so well enough, that it all sounded the same.

I filed a flat in the bolt to allow free travel of the knob, and wacked some primers......loooooks like I need to reset my firing pin protrusion... actually wacked one hard enough to dent the start of the case shoulder.

I only figgured this out last night after having a failure to fire day before yesterday, with what looked like a light strike.
Shot 30ish rounds with about 20 going into the group right at dark....I also peppered everything with my new 6.5grendel and my buddies .22, so there's holes all over.

Good hope that was the hole problem, still the chances of the things that went wrong are slim. Did you measure the pin portotion yet. I believe there are at .055 at the factory, good thing about the savage is the stops adjustable.
