Maybe I don’t know enough about steel and guns in general but there is no way that is “normal” or acceptable right?

    Rocking the PSR at the Snipershide Team Challenge.

    Got 4th out of 34 teams, despite @hic28 not being able to use his AXMC cause factory Hornady 6.5PRC decided not to make it pass 200y without 147’s blowing up. So he had to use couple loaner rifles to compete in the match....

    You could call AINA or Mile High and see if they can swap just the bolt head rather than buy an entire assembly.

    Also, if you end up buying an entire new bolt I bet you could sell the old bolt to someone wanting to do the 223 conversion.

    Yeah the bolt head would definitely be a option. However both me and him are interested in the 223 conversion anyways. So might be going that route sooner than later.


    I'm not so sure it's a Winchester problem and if so do you think all that damage was done in one setting? I shoot mostly Federal 210M primers in .308 and .260 and never heavy loads. I've never had a primer blow out or show signs of high pressure, and the original owner only shot about 700 rounds of new factory ammo and sent this in for warranty in 2017 when it was smaller. He was told it was okay and returned to him. I just noticed mine has gotten worse and looks more like a material problem of inclusions or porosity in the bolt head.

    Definitely didn’t have any wear prior to this one trip. Both his AI and my AI have less than 1000 rounds on them. And they definitely didn’t have any marks on the bolt head like that prior to this one range day shooting Winchester primers. Wish I had photos of his bolt head and the brass to show y’all. His bolt had multiple craters. Not as bad as I have or yours did. But still.

    Wow

    How many people have experienced this?

    Planning on getting AI AXMC/AXSR next year. I've been lukring this site for almost a decade and this is the first I'm seeing or even hearing of this.

    Also,

    Excuse my lack of knowledge but can you gents provide insight on who/where the .223 parts come from? Any links or info would be helpful

    I bought my AT used. Thousands of rounds thru it when I got it. '14 model. It already had some pitting from pierced primers from the previous owner. It looked like this when I got it. I've pierced about 20-30 primers from shooting 6GT and they haven't added to the pitting. The difference in my uneducated estimate is piercing a primer from using LRP firing pins on SRP primers opens the center of the primer. Overpressuring a case and having hot gasses push past the outside diameter of the primer/ inside diameter of the primer pocket is what caused this pitting.

    I wouldn't be concerned about purchasing an AI because of some guys pitting their boltfaces. At least not anymore than normal considering how expensive everything on it is. If you want to play with AIs get ready for limited customer service, aftermarket accessories, and expensive replacement parts. Just part of the game with AI.

    It’s not a AI issue. It’s a Ammo issue. If my buddy was shooting factory ammo or had a different primer the issue wouldn’t of happened. So don’t let this stop you from getting a AI

    Are you saying the AXMC was causing pierced primers on the factory Hornady 6.5 PRC ammo? If so, why would that be happening? Large firing pin? Or were you saying something else? Congrats on the 4th place finish!

    He's talking about the infamous Hornady 147gr ELDM bullet problem. Jackets coming apart and bullets blowing up in flight

    Oh gotcha. Hadn’t heard about that issue. Thanks!

    Some barrels can spin them too quickly, if the MV is way up there... Projectiles literally ripping apart and turning into dust. Need to either slow down, change to a slower twist rate or change projectiles.

    I'm building a 6.5 PRC hunting rifle right now with a 1:7.5 proof, hoping to only shoot factory Hornady precision hunter ammo... Fingers crossed.

    @96C A boat load of rifles went down last weekend at the NF ELR Match and a few this weekend at the SH Team Match.
    Most that I know, guys were either running factory Hornady ammo or bullets.
    For 6.5PRC, didn’t matter if it was a 7.5 or 8 twist, Proof or Bartlein.
    There’s been many cases of Hornady Ammo or bullets not making it to the target. Or putting some infamous ‘banana’ holes on paper . RPM’s in the 285k or below.
    It’s a sight to see when they blow up 40y in front of the barrel.

    So a buddy borrowed my AI this weekend. Calls me on his way home letting me know he is gonna be buying me a new bolt. Turns out he has been using Winchester primers and they were bad. Had three go in my rifle before he noticed.

    Ouch... Winchester large rifle primers strike again. I torched a bolt on a Remington 700 in 22-250 a couple years ago with a bad batch of Winchester large rifle primers even though up to then the older batches never had any issues at all. I was too focused on blasting a very active field of ground squirrels to notice the little puffs of gas escaping-- about 30% of the primers were failing via pinholes right at the radius of the primer. One afternoon of shooting left a hell of a gas cutting ring on the bolt face. Replaced the bolt when I rebarreled the rifle.

    The gas cutting of the bolt face from primer leakage is really more of a cosmetic issue than a safety issue until it gets either deep enough to weaken the bolt (doubtful) or the craters get large/deep enough to leave the circumference of the primer unsupported which can promote even more frequent primer failures at the radius of the primer.

    Very stand up of your buddy to replace your bolt!

    yeah im not overly concerned about it all. he doesnt currently have the money but he wants to order me one like now. Especially as I have a match on the 11th of next month. He has gone through the proper channels with winchester and we are waiting to hear from them. But I don't have high expectations.

    What is the purpose of the threaded cap on my factory flash hider. My AI/AT has that. My AX does not.I am sure one of you smart folk can tell me why. The cap comes loose after a shooting session, I always check that is tight be fore I use rifle. Curious as to what the heck the threaded end of the flash hider could be used for.

    Some sweet AI action all weekend at Vortex Sandstorm. Big thanks to Greg for taking all the photos.

    I’m really enjoying “gaming” the big matches and shooting the 20” 308 at shorter range matches with nothing but an Armageddon gear game changer and bipod.

    Are any of you guys running the .223 conversion kit? If so what are you experiences like? I have an AT I’m really Interested in getting one for.

    Shot at my sand pit on Monday, it was in the 90s and brutal. AXSA 6.5 x 47 factory Lapua 139s, put a 100 rounds total through it.

    First two groups are with the Tangent, 3rd group is with the S&B having a problem with the mount or the scope, not sure which. Gonna swap out the quick release mount to nut model. See if that makes a difference. Nearly all the groups are like this with the S&B.

    Been going back and forth between these two scopes trying to figure out shy the S&B consistently does poorer.

    @BuLLet you can convert your era tac mount over to a non QD attachment, no need to buy a new one. Call up euro optic and talk to Jason.

    Hey guys,
    Does anyone know what size these screws are on the underside of the AXMC firing pin assembly are? I've got one that is close to being stripped (the assembly i sent to AI) and was hoping to grab a few spare screws.

    I got it at Scheels, you should be able to look it up on their online store.

    Pay no attention to @Huskydriver, he pads up like no one else at matches and stuff. I have witnesses... @kocustoms @tevan0707

    What can I say...I got sensitive knees...I'm not used to kneeling like some people........
