Failure to fire with AAC Ammunition

Good morning,

I have been scratching my head for a week now and have kind of hit a wall. I have a Zermatt/Big Horn TL3 SA Action in a Pork Sword Chassis build I am completing and for the life of me, I cannot get it to fire AAC ammo. It is chambered in 300 Blackout and the sole intention of this thing is to be a well-rounded garbage disposal. Here are the parts for anyone who may take the time to help me trouble shoot.

Action: Zermatt TL3-SA
Trigger: Geissele Super 700
Barrel: Black Collar Arms 9" 300BLK

Tools Used:
Zermatt Action Wrench
12pt 1-1/8 Crowfoot
Forster Go/No-Go Gauges.

Here is a picture of the build:

The left group (FTF) of ammo is all AAC (115gr, 110gr, 125gr SMK) and the right group (Fired) is Hornady, Sabre, S&B Tactical, Winchester Super Suppressed and Ammo Inc. Not Shown is the Hornady black.​

Sorry for the huge pictures, hopefully they give an idea. Here is what I tried:

I have rebuilt the action and head-spaced about three times, each giving the same result. It does not feel tight or "forced" when closing the bolt. I believe it is head spaced right.

I have changed the trigger out to a Triggertech Special Pro from the Geissele. I have read in other posts people remedied similar issues by swapping them out due to potential drag or sear issues. No change in results.

I field stripped the bolt and cleaned the spring and firing pin to eliminate any drag from debris or thick lubricants.

My guess? The primers are hard as hell.

Question is, what can I do?

Zermatt offered to remove material to allow for up to another 10 thou in travel for the firing pin but I am not sure that will fix this. When I pull the trigger on this ammo, it's a very distinct, soft "thud". When I headspaced, the extractor was removed, so I don't think I gave myself a false head space. I am no means a bolt action expert and I am at a point of confusion as to how I can get this thing to do what I need it to do. Any input is greatly appreciated. Anyone who may figure it out, you get some coffee on me.

August is National Shooting Sports Month... where's the parades?

Shouldn't the media be all about promoting Shooting sports? Don't we get to dress up in funny clothes and have parades? How about Shooting Story Hour where we get to go to schools and tell hunting stories or how we capped some tango at 800 yards? How about having companies pander to us with special ad campaigns celebrating shooting shit?

WTF... we have a whole month and they act like we are a bunch of pariah's.

Ok... this is America. Ever month should be Shooting Sports Month. But if they can have a whole month for gay cripples and transvetite eskimos and black Siamese twin hermaphrodites.... can't we get at least a decent parade?

AI AX308 barrel identification

Hello,

Trying to identify this barrel manufacturer. Photos attached

I believe it’s the original barrel from a AX308, post ‘14. Looks like it was chopped to 24” from 26” at some point and has remnants of the flats with 308 marking.

It has a CW prefix serial.

Is this a Bartlien?

Thanks,
Ian

Ramshot TAC questions

Today I believe to have ran into my first hurtle with ramshot tac. Being a ball powder and not temp stable how much of a temperature swing cause issues. 5, 10, 20 degrees. I never took temperatures on my first load development this summer. Va hot and humid. Today was 60 degrees when i was shooting. This tells me i need info at certain temperatures if i am thinking correct. Also had my first run in with mirage. Hats of to those compete in shooting or just having fun. Stay there for a got while just watching the mirage affect my glass. Oh and shooting 69gr smk out of a 16" WOA spr barrel.

Broken Election Promises and Hypocrisy: An Apolitical List

Here is a thread where we can track and discuss things politicians at any time and in any political party promised, but failed to deliver on.

I will start.

Obama the first time said something like “Sixteen brigades in Iraq, one brigade per month, the U.S. is out of Iraq in sixteen months.”

And not necessarily a broken promise, but John McCain voting against the Post-9/11 G.I. Bill was a betrayal.

ARC 30 MOA Coup de Gras action with PVA 26" stainless M24 barrel and Timney Hit trigger-$2075 cost, sell for $1950 TYFFL

MDT XRS chassis with Area 419 Pic rail and 2 magazines $860 cost sell for $625 TYD

If broken up barreled action must sell first or I'll just keep it.

I also have a considerable amount of Hornady Ammo to negotiate with. Not really looking for trades but if you make me a deal of the century who knows.

The coming tantrum

While I thought Kamala’s concession speech was pretty good about not being divisive (she still made some low key jabs in the second half) the ultra left are still losing their shit and Inauguration Day is going to get seriously sporty in and around DC! We have a group chat with my brothers and cousins and the one pink haired cousin despite the no politics or religion rule is LOSING HER SHIT at anyone and everyone who didn’t adamantly oppose the orange bad man to the point that cousins are leaving the group. If her behavior is remotely representative of the ultra left they may seriously regret authorizing the National Guard getting involved on Inauguration Day.

Not to be left out...Kali


I guess he didn't want the gov of MA to get all the glory.

I predict Social Unrest will be cued up soon!

I hope I am wrong, but I got a feeling BLM, ANTIFA, LBGQTB+ have been put on standby.

They are just waiting for the next George Floyd event to happen and start burning down cities again in the name of social justice.

The MSM is will do everything possible to make Trump and his garbage deplorable’s responsible for any inequality or so-called injustice.

I bet the FBI has somebody they’ve been grooming/watching for the next mass shooting, don’t worry it’ll be some deranged white guy with no social media history wearing some sort of right wing T-shirt or hat.

Like I said, I hope I’m wrong.

This just feels too good.
