@jbuck88 i have run 6BR in AI’s (AX and ATX) for 3 or so years and have a couple thousand rounds through the actions. Zero feeding or ejection issues. I run the HRD Gear 6mm Mag Spacer Kit with AX mags.
Do you have experience with it? Or why do you suggest the 6gt? I'm hoping for some first hand experience as it'll be gearing up to load a whole new cartridge, unless I stick to light loaded 6cm. So hoping to make the most of it and get something that's reliable enough for my kids to shoot and not have to mess with too much. I do have a bunch of AX mags. So I could theoretically go thru them to try and find a reliable couple if needed.
Nope. But it has factory ammo available and I hear it feeds good
For non western matches I guess br would be the way to go. If it feeds.
GT can definitely have feeding issues in AT-X. Mine is a 22 but it’s the same exact case and the bolt will absolutely skip over rounds if you load them all the way to the rear. They have to be moved forward in AX mags so the shoulder interfaces with the rib, but there are no spacers that currently work with the GT case. I’m also not the only one that’s experienced this issue.
AI basically says “it was not designed to work with GT cases” so they won’t guarantee that them modifying the mags will fix the issue. I did try moving the feed lips slightly but it didn’t do much to change anything for me. I also think shimming the mag latch would likely fix the issue altogether.
Personally I’d stick to Creed/X47 cases or BR/Dasher as the HRD kits are well-proven too.

I'd go with a straight 6BR with HRD spacers or the slow 6CM option based on your criteria. I shoot 6 Dasher and as long as I run the bolt home with moderate speed I don't get nosedives (I'm using HRD spacers.) Straight BR would be easier on barrels, Lapua brass is available, factory ammo, and off the shelf barrels.
I recall 6 GT AT-X shooters saying they need to position rounds in their mags in a special way lined up with a rib or something similar. I'd look into that more before diving into a 6 GT.

@jbuck88 @just browsing
@jwood1284 has run 6XC in an AT/AX with unmodified mags for a couple years with no issues.
I had some older AX mags that had issues with 6.5CM, apparently the tolerances are different depending on when they were made. I eventually sent them back to AI for them to modify the feedlips, and they work flawlessly now.
But, as a quick fix i used my 6BR AX mags. I removed the back spacer on the HRD Gear 6mm Mag Kits and ran 6.5CM in my AX Mags with 6mm Mag kit. The follower forces the entire case to sit higher and specifically the nose of the round to be angled further upward. I had zero issues with this and ran the entire Arena Guardian match like this.
I suspect a GT, CM, x47, XC would feed "better" with the mag spacers. There are more or less all variations of the same thing.
100% agreed - moving the rounds forward in the magazine as a spacer would seems to mitigate the skip over issue… the problem is (at least as far as I’m aware) that there are no spacers or followers that work with GT/x47L/Creed length cases. They are all slightly too thick to allow the shoulder to fit “inside” the forward rib of the mag.
ETA: you’ll also run into seating depth issues with the longer cases, at least with heavy bullets.

22GT as mentioned above has to be slid forward to get it to feed reliably. Found that out the hard way and prior, kept me from shooting it for several months. I've had no hang ups with my dasher in one mag but the other mag has problems where the rounds will nose dive in the magazine. Mildly inconvenient but what can you do.
Well that new 6.5CM Norma 143 ammo is rather tasty according to my ATX...almost 1/8MOA!
Was checking the offset for new ammo type and very first 3 shots basically stacked on each other. (so much for cold bore...?) $1.15/rd too FFS

Well that just turns me on! I bought a few rounds of it a while back for emergency situations because it was stupid cheap.

Right on, I only got 800 but its definitely my new favorite factory ammo, free shipping from these guys:
Norma Precision 6.5 Creedmoor 143gr BTHP Match ammo 2723 FPS 2355 FT/LB 20/box
Norma Precision 6.5 Creedmoor 143gr BTHP Match ammo 2723 FPS 2355 FT/LB 20/box

Seems like a majority of factory ammo is hammering in the factory 6.5 barrels.
Berger, Hornady, and now the Norma Precision stuff have all reported excellent results.

Norma seems to be good stuff. Shot ridiculous from my XM3. For $1.28 a round to my door no less. Was damn near the same as me buying 200pcs of norma brass.
On the topic of the magazine. As i mentioned last weekend I’ve had some issues sliding over myself with my aw mag and my tempest in the atx. I have an AX mag to try now. But what is the function of the rib in the magwell? Cause i can see it hitting the case web and pushing my rounds into the mag cause less case head presentation.

Try removing it perhaps. It's for aics double stack single feed mags as thats what the atx 700 aics was designed for. I've been running arc mags with 6gt and 6bra throug arc archimedes and lpa fuzion in the atx700 chassis without a single misfeed. Also tested zero shift twice by removing the barreled action to adjust the bna trigger a couple times and my zero never shifted at all. I was impressed.
You're talking about the metal C shaped mag stop in the rear side of megazine inlet correct? Yes its bolted into place.
Waiting to Practice 2 days before a match always works well lol
How many times you changing your name Burt??
Don't forget, Rengage
Rem700 .223 with some upgrades. Side bolt release, 8-40 base screws, blueprinted, one piece bolt, etc. I wanted the rem700 to use the AI scope rail so it would run continuous and match up to the rail on the bridge. 24” MTU barrel.
Yeah, so far, so good. Just ran some ammo from another gun to get some rounds down the pipe. She feels good. With the 3 internal weights, she’s exactly 20lbs with glass.
Rail and some hoptics stuff came in. Does hit though. I’ll have to sand a little bit of the 20 MOA rail.
Just ordered the AT-X in 6.5creed from Eurooptic.
Does anyone know if the 700 ATX chassis with fit an Impact 737r without having to mill out a space for the trigger hanger?
Yeah you should be good. Lots of room around the trigger area.
It will my tempest has a large trigger hanger and isn’t exactly straight 700 clone and it fits well
Off topic but how do you like the recon 2 with the anvil head? Does it come loose on you when panning?
It’s my first tripod setup but I’m loving it. It hasn’t come lose panning but if you lock it and go left it will. I’m just gonna put some blue loctite on there to prevent that from happening though
What is the model number for the AT-x magazine? The body is similar to my AX mags, but the follower is completely different.
Did you remove the rear mag block installed in the chassis to see if it helped with your aw mags yet?
Oh yeah I did today. Completely solved the issue. I should've posted it.
There is no change it’s still good and tight. Ax mag i bought also works well. It doesn’t adjust the latch or tension at all
My kid approves. Need to cycle it a bunch to get it broke in now. My AX is noticeably smoother.
