We’ve just heard from AI that our AX50 order is expected to arrive this September! If you’re interested in one of these rifles, feel free to send me a message or check them out here!

Great rifle, but good Lord that price tag!

I also don’t understand why they would completely neuter the rifle but cutting off the other nut. 50BMG was designed By JM Browning for a 45 inch barrel and the industry standard 29” gives up a lot of horsepower. 27 inches for a 50? Is it a close, quarters battle rifle? The AX50-Eunuch :)

Yeah, you take the highly capable 50 BMG round, you neuter the barrel, make it lightweight (26#) with brutal recoil (three (3!) port brake), and install a 3 1/2 pound trigger and call it a “ELR“ rig. Which is flat out silly unless Hummers/APCs at 1000 yards is your idea of “ELR“. More like an “extreme flinch generation” rig.

Now the idea of switch barrel for 375 might make it a viable rig, but you’re gonna pay 15 K for the 50 caliber version while you await a $5000 or more conversion kit?

Actual DOPE from my (100% stock, except for a grip change) AX50 ELR shooting factory 750AMAXes (Did Browning have 750AMAXES?). Doesn't even hit transonic until about 1 mile, and people successfully load for AMAXes way hotter than factory.

ETA: Oh, and that energy number at 2100 is the equivalent of a 300gr Scenar loaded at book max for .338LM (27" TRG42) at 1050 yards. Have you seen 1,000 yd impacts from a hot 338 Lapua? I suspect you have, so you know the kind of energy they're carrying.

I have definitely been eyeing them, a cheytac bolt would make me hop on it for sure....I should have my TBAC Ultra 50 in a few days to play with on the 37xc, but man it would be so much more of a cool factor hanging off the AX ELR....
 
There is a guy on here. I forget his name that posted pictures of that rig with that can, and I don’t think he is 6’5” but it is still taller than he is assembled.

And it is no chance occurrence that TBAC uses the AI as their test rig given it’s (too, IMHO) short barrel. 27 inches might actually be the right length for that can. And I allow that everybody has a 50 for a different purpose, mine is to optimize ballistic performance.

Everybody I know with 29 and 30 inch barrels in real life gets about 2600 ft./s at a factory AMAX, and my guess would be the AX50 is doing 2550 tops. I can’t see if you have the muzzle velocity in your chart above.

I get about 2840 out of a 40 inch barrel with 236 grains of RL 50 which is kind of the standard load for the FCSA shooters and some of the custom ammo loading companies. You can go hotter, of course, but I prefer to stay deep within the safe load zone with mine

And yes, here is a 285 ELD going 2940 ft./s out of a 32 inch barrel at just shy of 1100 yards on a 12 inch 3/8 plate. 338 is no joke but it ain’t no 50 either.

AX50 ELR gets 2585 FPS (mean). I took a video of me chronographing one shot back when I was still using the Labradar:

I am 5'11''. Yes, the complete rifle is taller than I am.

Hindsight being 20/20 and all, I should have had MHSA shorten the AI barrel when they threaded and put the brake on this. Even if I am losing a little velocity, I can add a few clicks and be good. The targets arent shooting back.

When this barrel is toast, I will for sure go shorter.

Well, to be honest switch barrel if it is a good system, it’s quite useful unless of course you intend it as a dedicated 50 BMG which limits it’s usefulness because you don’t always want to shoot 50BMG and sometimes range and other restrictions prevent you from doing so, forcing you to leave your 20,000+ dollar scope/rifle combo in the safe or the drag bag

40 MO a rail? Meh

Connor, are there any news about .375 CT kit?

I mean it’s really not much more than the AXSR. 🤣
Resale Value. This will be especially true when the .375CT (etc) conversion kits become available, which I'm 100% positive will be any day now. 100% positive.
Now we know where IP Trickler fella got his go to market strategy.

How’s it sound suppressed?
 
I spoke with Brian yesterday about it. He has the only factory demo bolt. Sounds like he literally has no clue when it will be released. Says it works great. Also said he's not sure he'd go out and buy an AX at the moment in hopes the 375 bolt is released soon, because it could very well be another year...or more.

Nice to see it in action, but ya who knows.
 
watched the video, could use some editing but they get credit for even trying in those winds. Looks like the TBAC can with one section removed performs quite well. But 2960 from a 27" barrel with N570, JFC, they're going to deep-throat that pipe in one or two matches. I get 2870 from a 35" pipe with H50BMG and the 410 Bergers

Well it’s good to know that one actually exists however it sucks to know that it could be another year or two before they are commercially available.

Right, that is the crappy part.

It might be slow, but i was going to shoot for are 2850ish range with the 410 berger & H50BMG when they show up. If i don't get H50 working, I'm gonna go to n570, but keep it slower. This is with 37XC, not Cheytac
