Accuracy International AT-X

Rifle at 24 lbs.
(too poor to have a Raptar and need a Raptar mount so MRDS is at 12 O'c.)

Forgive the newbish question here but what other calibers can you run on the AT-X looking into a Proof Carbon barrel for hunting to save a bit of weight and wondering what options are on the table. My understanding is anything within the 308 family of calibers but is that it? Are any of the PRC chamberings possible or is it just the ones below from the "308 family" ?
  • 243 Win
  • 260 Rem
  • 7mm-08 Rem
  • 308 Win
  • 338 Federal
  • 358 Win

Um 6 and 6.5 Creedmoor aka the best cartridges for everything.

You can't shoot any PRC cartridges on the factory bolt due to the larger rim.

The biggest case you can shoot off a standard bolt face in a short action would be the 284win case. But you run into issues with overall length.

You can get an aftermarket magnum bolt face from bugholes, or wait for the factory bolt (but that could be years away or never come at all).

Admittedly looking at the extended rail of my tempest I'm worried about the full length forend fitting under that gap. Think I might have to switch rails.
I think you'll be okay? There's a gap between the long bridge and the action. This is the atx aics chassis with bridge and folder, Archimedes and HH heavy comp 6gt barrel.

Back at it again.

Question though I’m having some feeding issues with my AW mag. Which I’ve ran an AW with my tempest since the guns inception. Is there a way to adjust the mag release or do i need to get an atx mag?

I’ve had better luck with AX mag. It has that hook on front that seems to hold the mag up and tighter. I did have to slightly open mag lips up a bit to get the rounds up high enough.

BTW if you run a HRD mag spacer for the BR family you have to slightly modify the rear spacer piece so it doesn’t interfere with the mag stop on the atx chassis.

I've got a buddy who's gonna sell me an AX mag so I'll give it a shot. I'm running 6.5x47 so should be fine. Is the mag latch adjustable?
 
Kinda dumb that they haven’t figured out that an adjustable mag latch would resolve probably 95% of their documented feeding issues, but… a lot of what they do doesn’t make any sense so I guess I’m not really surprised.

@5RWill it may be worth sending your mags in to AINA to have them checked/tweaked and ensure they are “within spec.” There was a run of AWs a while back that had some geometry issues so they will look at them if you ask.

I had plenty issues with feeding before i opened up the mags. since then, AX & AW mags have run floorless with both 6BR and 6.5CM. Amazing that one 2 min job has resulted in zero feeding issues. Cheers
 
I’ll have to try that.

I’ve got 5 mags and every single one will fail to feed. It went from a mild annoyance to wtf.

I didn’t really want to “tune” my mags for a 4K rifle. But with 6cm, 6.5cm and sometimes even 308 the bolt slides right over. I pulled the springs to add more tension and that did nothing.

Someone was talking at the range, I didn’t catch it all but they said in the Gen 2, accessing the trigger housing was made easier? Also the Gen 2s fixed the feeding problems?

Is there a reference to the updates from gen 1-3? Not that it benefits me as a poor ol gen 1 guy.

A friend of mine got the info from Scott S. Mines Gen1, open up in middle near rib, to match measurement at base (usually 1.5-2mm needed), Done. HRD kits run floorless, AX/AW etc. Been discussed few times on here. Cheers.

We don't speak about AT-X magazine issues here, it might summon @Scott Seigmund

So I’ve never had feeding issues with the aw for 6 years now with the tempest which is why i think it’s a latch issue. But I’ll see if the AX mag fixes it.

Well this is the chassis which was designed for 700s so the latch is probably set for AICS mags, thinking about it.

It is called the atx aics chassis, I'm not surprised AW/AX mags are troublesome. I know my ARC aics mags run great with the 3 lug ARC actions, as well with my zermatt actions in br, gt and creed cases, zero mag tuning required.

Yeah so it will likely need adjusting. The tempest was pretty much designed for the AW though. One of the perks of 3-lugs is running a double stack double feed AW. Wonder if i can remove it and have it filed down I’m sure i can. I had to do that for all my manners for the AW mag.

Do you think the mags riding too high? Too low? The AX mag will fit with nose higher as the front lip will help that. If your bolt is riding over rounds, you need more case head presentation which requires a taller mag latch or modding feed lips to gwt rounds up higher. DSDF mags can be tricky.

Bolt is riding over. Which i can see the case head isn’t being picked up by the bolt. With a full mag it only happens on one round. So maybe it’s going to require some feed lip adjusting. I’m gonna see how the ax works out if that resolves I’ll sell the AW.

That’s my issue as well. Happened with my AX mags including the one it came with.
 
I haven't read all the pages of this thread so my apologies if this is a repeat question....
But who is the genius that thought of selling the AT-X ONLY in 6.5 Creedmoor? The vast majority of shooters in PRS shoot a 6mm bullet and there's no factory 6mm options? So one must pay $5200 ish for a rifle then drop almost a Grand on a barrel if they don't want to shoot a 6.5 Cr?

I’d imagine other calibers will be released. Eventually. It’s AI

In the meantime. Cut the 6.5 down for hunting or sell for $500-650

Hadn’t checked in for a long while. Still shocked this thread got big and I haven’t come even close to reading them all. Need to take some actual glamor shots of the rifle but it’s got some new parts since I got it and just got my hinge last week. Been through (2) 6Creed barrels, almost done with a .308 Win barrel and halfway through my Proof Carbon 6 Creed barrel and she’s a well oiled, butter smooth machine. Biggest problem is keeping barrels lol

Who makes the shelf?
 
Had a buddy that’s pretty gangster with a 3D printer whip them up. He’s trying to get a solid template/prototype then I’m trying to convince him to sell them. This one is graphite, doesn’t weigh anything and stupid strong but really makes a difference on a bag
Nice looking rifle. I'll take a set or two of those baker wing clones! I just added the dependabilt lite weights to add some width to the forend, believe it added a pound but its perfectly centered weight so not a big deal.

That’s exactly what I’m looking for, please make it happen.

Already tracking the lighter weight option from Sawtooth but there’s still a small weight penalty being metallic.

Hell I’ll print it myself, I’ll pay for just the model.

My AT-X has shipped. So now time to figure out what to do with it.

Do any of the 6mm BR, BRA, Dasher, GT feed better then another? See that AI has 6br barrels available and Milehigh has 6dasher and 6gt barrels. Or would it be best to just download the 6cm? Goal would be a light recoiling rifle for the kids to play with.

I understand that the 6br, bra and dasher would need a kit for the mags. Any kits better then the others?
