I wonder if its forwards compatible with the AT-XC with its new bolt and action features? I also have been using the standard AX magazines, anyone know what problems this one is supposed to address for the AT-X over using the AX magazines?

I’m not exactly sure, but both magazines I have for my ATX had issues with feeding 6.5CM and occasionally rounds would pop out of the magazine when inserting it. I sent both to AI and they adjusted the lips and I think they replaced both inserts as well because one of my magazines (the heavily used one) came back with a new insert. The other magazine’s insert, I couldn’t tell if it replaced because it was a new magazine.
I suspect that’s part of the optimization.

Looks like they made some machining cuts to either side of the action to lighten the action.

how do we fill this giant weight reduction hole in the receiver/rail? im not a fan of it and prefer the Gen3 action look.
 
I’m about to step out the door and do exactly that while the weather is still nice and the range isn’t a mud hole.

That's the unit I want I just need to find someone who ships here. The paracord was just to get me out of the house with a sling haha.

It's been covered to death but I would describe the bolt lift as stiff with the detent positions being quite noticeable. My AE is noticeably smoother after well over 100,000 cycles so I am sure it will break in.

I'm sure everyone knows what they look like at this point but here is mine. Waiting on a handguard wrap, stock hinge, Deluxe Ergo Grip, sling swivels, and magazines.

I thought the silver/gold Heathen 2 looked kind of gaudy. It looks like a deadbolt latch. 😅 Hopefully it works well.

Does the cut in the AE forward of the mag well make much difference in how the rifle sits on a barricade?
I‘d thought about the ability to do this on the AE/AW and how it would easily “modernise” the chassis.

Yes without a bag, or sometimes with the sling thrown under it, it made a great impromptu barricade press that allowed it to sit flat. I really liked it for big fence posts and my Hog Saddle as you can see in the picture.

Not my original idea though. Someone, possibly on the hide a decade ago, made a little tutorial on cutting a barricade press slot like that in Viper Skins and that inspired me. It isn't solid plastic so it was pretty easy.

Has anybody ever had issues with Federal 6.5 Creedmoor ammo in their AI or other rifles? Hit the range yesterday and fired 3 rounds of 130gr Terminal Ascent, which is loaded in small rifle primer brass, all the primers looked like shit and one of them backed out a smidge. When I got home and cleaned the rifle I discovered a bit of carbon on the firing pin, so I guess the one that backed out must have released some gas.

Everything else functioned just fine, although a few of the Hornady 140gr ELD-M seemed like they might have had slightly harder bolt lift than the others. No issues at all with any primers in the large rifle primer brass.

This particular barrel continues to display an affinity for Hornady ELD-M’s.

When you say looked like shit are you talking cratering? I see you have SFP bolt already. We ran CCI 450 in my buddies rifle. They have a harder cup on them and didn’t crater once the firing pin hole was bushed

Have you checked the headspace?
 
Yes cratering.

I don’t have a headspace gauge, but fired brass was .005” longer than unfired measured with the SAC comparator on a Lyman dial caliper.
 
Complain to Federal, its bad ammo design to be using SRPs .308 boltface hunting cartridge.
 
Federal won’t give a shit most likely.

A bit more comparing it looks like the Federal brass is about .001” shorter on some pieces than Hornady. My Fired Hornady cases expanded only .004”. Same story for the Berger I shot in Lapua brass.

As a precaution I pulled the barrel, removed the top bridge to expose the front of the receiver and threads. I then thoroughly scrubbed the barrel shoulder, barrel tenon threads, receiver face, and the threaded portion of the receiver that accepts the barrel. I had recently had the barrel off to install the top bridge (which I just now discovered is not necessary) so there’s a possibility that some bit of debris was interfering with those mating surfaces. I then reinstalled everything and used a wrench to ever so slightly snug up the barrel into the receiver so headspace is biased towards being more minimum than maximum.

I will now torque the barrel lock nut to 55in-lbs, and reinstall the top bridge and torque those fasteners to spec.

I’m sure it’s not your issue but if you just cleaned it make sure you don’t have residual oil in the chamber.

Also federal is soft brass. Hornady isn’t a ton better. So factory ammo loaded hot or close to the lands could have some effect.

Also remember you’re part of the #12lbsboltliftgang with that ATX. So maybe the hornady is just fine 🤪
 
This rifle loves Hornady ammo for some reason. Berger factory ammo is OK, everything is sub minute, but this particular Bartlein LOVES ELD-M’s.

The Federal stuff shot reasonably well for hunting ammo just seems like it might be loaded on the spicy side. Which probably means it should be running large rifle primers. That said I torched of 3 rounds of 129gr Hornady SST “Superformance” and it shot better than the fancy pants Federal stuff, and showed no signs of pressure or primer issues.

I guess I should be happy it likes the cheapest readily available component match bullets and loaded match ammo out there. Like a pretty girl that would rather drink Coors Banquet than Champagne.

@RUN8 did the boltface or firing pin get etched? Was there evidence on any of the spent cases of leakage around the primer, or piercing? If factory ammo were etching AI parts, I'd be very vocal with the ammo manufacturer.

If the Federal ammo is leaking or setting the primer back it is worth calling them in the event there is a bad lot out there. Hopefully you still have the offending box with the lot number.

I don't see any recall info on the Federal website. That might just be my web surfing skills.
 
Still have the box and the remaining 16 rounds, I had fired a single round of it back in November at a steel target using the same elevation as some Berger 144gr and it hit to the same POI as the Berger at 523 yards oddly enough.

I see no evidence of bolt face or firing pin etching, just a bit of carbon on the firing pin tip and I noticed a bit of smoke at the rear of the bolt where the firing pin tail protrudes from the bolt shroud. Otherwise I wouldn't have paid much attention to it.

I did leave Federal a report with pertinent details. The lot number of my box is B046U18 in case anyone else has any on hand to be on the lookout for.

Rumor is cold weather causing ignition issues with srp in larger cartridges

What’s a more likely scenario is cold weather causing lube in the ignition system to thicken up and create more drag, robbing energy transfer to the primer cup.

Key word was rumor. Was going around a while back. Guys were swapping to small rifle magnum primers

I'm only in to ask if people have had problems with factory 6.5x47 Lapua. I don't think it has ever been sold as anything but small rifle primer.

I have both large and small rifle primer brass for my 6.5 CM and 6XC, never have bought any srp 308 brass. But, that's more of a hedge against primer availability than anything else. I don't load high enough to need srp.

I haven’t read about any primer issues with 6.5X47 Lapua.

From what I hear it is the proverbial “easy button” of 6.5mm cartridges to load for and achieve single digit SD’s.

It’s a well designed cartridge with the huge advantage of only being available in top quality brass, and that is going to help a lot.

I traded it for a Utc-x.

So

We all have our own opinions of price.

But comparing a Lwts lr that msrp for $25000 and was fire saled by dealers for no less than $14000. And I listed for $10000

Is slightly different than listed a $5250 msrp rifle that fire saled for what $4250. For $4250. Minus the $120 mag and $6-900 barrel but adding a $250 hinge.



Yeah totally comparable

So I’m the angry one cause I’m clapping back? 😂

Find me the fire sale… I’ll wait.
Dudes were dumping AT-X for dirt cheap cause of EO’s and MH’s prices. Now they’re gone.

Everyone is crying about that $6.5k pricing on AT-XC.
But I’m smoking crack for my listing? You’re comical


There’s another AT-X with all the bells and whistles for $6k if it’ll make you feel better.

I am not sure which AI you are using but this happens to me all of the time in the AXMC which has a LFP. I don't use terminal ascent but use the FGMM with the Berger 130-grain bullet. Primers are badly cratered. Sometimes they are even damaged to the point where fragments end up preventing the firing pin from working. I have to take the firing pin out and dump the fragments out of the bolt body. It also coats the spring with all sorts of gunk that requires a thorough scrubbing to remove the residue. Norma 6.5 with large rifle primers is even worse than the Federal. I want to try the Berger-loaded ammo since it uses an LRP to see if that works without issue.

I have stopped using Federal and Norma in the AXMC. Like you, I am thankful that the AXMC does not exhibit this issue with Hornady and like you the groups are great so I just use that. My AT which has an SFP does not have these issues so I run the Federal in that.
