Anyone have an idea on the writing on top of action ?

I just noticed it in this pic and will remove mount to see more

Also anyone know why there could be a possible check mark on top of bolt ?

Import marks before they started putting them on the side. Oak Ridge around that time.

The tick is probably just sharpie. Use isopropyl to wipe it off. Don’t think too hard into it…

There have been several importers over the years. I dont know the list. Probably corresponds to the year of import.

Seems like a research project someone should look into and publish.

98 = Oak Ridge?
06 = Mingus
95 = Gunsite

Had some fun at NRA Whittington with my AT-X a few weeks back. Shot out to 1900 yards and tried to connect at 2050 but ran out of elevation and the wind was going crazy. The round 1 mile target is 30" and we put a beating on it as you can see. Super happy with the AI and the experience at Whittington is highly recommended

After 5 months of being a safe queen finally shot the AT today.

Not nice tiny groups to show off but the rifle is a joy to shoot. The mighty 308 is a little hard to keep on target for spotting impacts/misses, but considering it was was first few boxes of ammo through it, I felt it did alright.

I like shooting 308. I reload 308. And that’s the only way to push and maybe keep up with 6-6.5 mm lineups is to reload them. Other than that, factory ammo 308 suck at distance.
Click to expand...
I don't mind the challenge at longer distances.

I don't reload, so caliber makes little difference in terms of available factory-loaded ammunition. I can get .308 factory-loaded that has comparable SDs to factory-loaded 6.5 CM. 6.5 CM is a better LR round due to higher BC bullets. Higher BC bullets in .308 would be great, but I can't see that happening.

I have a question for the learned AI experts to help understand an issue with my AXMC using my new 300 WM bolt.

I configured the MC with the new bolt body, a new AI 300 PRC barrel, and a new magazine that has been tuned for 300 PRC (red follower). I went to zero it today. The rifle performed well in terms of accuracy. I had it zeroed in 3 shots. I used Hornady 300 PRC ammo with the 225-grain bullet. Before I began the process, I loaded the magazine, put the safety in the middle position, and cycled the bolt to check feeding and extraction. All of the rounds loaded and extracted perfectly. The bolt ran smoothly during chambering and extraction.

I then began the zeroing process. I fired one round, and was pleasantly surprised that the POI was minimally different than when shooting .308. Here is where the issue began. After firing, cycling the bolt required considerable force to open it fully. It went up to a point close to the top, but then required excessive force to lock it in the open position so I could extract the fired cartridge. I fired a total of 15 cartridges. All required extra effort to lock the bolt open, so it could extract the round. Some required more force than others.

I measured fired and unfired cartridges, and dimensionally, they were almost identical. The only measurement that was different was the diameter of the neck. An unfired case measured 0.338" while the fired case neck diameter measured 0.345". I don't know if that is normal since I don't reload.

Any thoughts?

Over pressure?

Got a pic of the rear of the cases? Primer area

TY!!

These rounds are factory, though. What would cause the overpressure?
Click to expand...
Factory rounds can have over pressure. Try a lighter grain. I’ve seen 6.5 CM have issues in some guns with factory ammo as well

After trying 6.5 CM and 300 PRC I seen pressure issues and went back to my 260 and would go back to 300 WM throated longer if I went back to a long action mag again

But then again.. other things to consider. Hornady brass is not the greatest either. I don’t use Hornady brass but I’ve heard they are soft an thin. So the pressure could be expanding out to the base of the case as well. Causing such over pressure signs. I wouldn’t worry about it imo. I say you should be fine shooting them. I mean you don’t reload so your just gonna toss those factory brass anyways. But if you ever do reload, buy Lapua and don’t reload range picked brass.

That is why I want to try the Berger 215. It is loaded with Lapua brass.

I have seen more then one 300 PRC have the same issue with factory ammo. I have read somewhere long time ago 300 PRC not liking it with higher pressure, depends on the chamber. Doesnt help that it's Hornady ammo. They are notorious for having shit brass.

What the hell dude? For a couple of years I’ve been listening to you trying to find that bolt body, and you’re gonna blow it up first day?

All joking aside, there was a guy in Franks class last year at Black Bear and I’m pretty sure he was shooting a 300 PRC, and he was using factory Hornady ammo and was blowing the primers. Actually had one cause a failure to fire because a blown primer got stuck in the trigger. Not sure what grain, sorry

Good luck with your Berger. You’ve been waiting too long for this

Could also be jammed in the lans, or carbon ring if you barrel is dirty. Not saying yours is.

Could also be excessive headspace forcing the brass back, no?

Granted I still haven’t played with my 300 PRC AXSR, but the Hornady I bought last year and shot in my MRAD had zero issues. I’m a little loathe to the get the AXSR setup as I’m still contemplating the need for it and the boxed TT735P JTAC when I have no good opportunities to take advantage of the cartridge.
 
#23,785
@Nik H I have a 22-250 barrel on my AT, and with one box of Hornady Superperformance 50gr there were a bunch of quite hard bolt lift cycles. So much so that I gave up and tossed the six remaining unfired rounds into the dud can at the range.

The other boxes of that stuff that I had fired more normally, although there were a few slightly harder than normal bolt lift events. Just a little.

The boxes of the less high strung Varmint Express 50gr that I also shot through it were fine.

So yeah, Hornady can suck, for sure.

I know, right?

Thanks for the chuckle.

All I kept thinking about when pushing up on the bolt was what @carbonbased said when I posted about getting the bolt. He said, "Cue to all your bolt handles snapping off in 1…2…3…"

It is good to hear that others are having this problem. Much easier to solve than if the problem were due to a machining issue with the bolt or barrel.

I'll let everyone know what happens when I can find some Berger.

Also, I'm looking for an IMUNS for the AT if anyone may know where to find one.

You mean monopod, right? Atlas, the bipod manufacturer, makes them. As far as the factory AI models (like AW) fitting at AT, I’m not sure.

Also, as an unpaid muppet, you’re gonna get banned for basically posting a WTB ad.

Yes, the factory AI buttspike monopods.

I'm a paid site supporter, thank you, and I was not "posting a WTB ad". I was asking if anyone had a lead to somewhere obscure that may have some hanging around in stock still. I've seen folks link to hard to find parts in this thread and others. if the mods have a problem with this, I'll happily remove it.

Apologies, I noticed you were “orange” and didn’t have a full member tag and jumped to conclusions. Sorry man.

Reasons like this are why I posted a thread in the admin section asking Frank to clarify the whole colors and tagging scheme. He admitted the system had degraded into a bit of chaos.

No worries. I think there's some site glitches. I still get a sidebar reminder to complete my profile and watch my first forum...both of which I've done long since.

Thanks...way more $$$ than Hornady

Oh, heck yes. One of the reasons I got my AXSR in 300PC - I already had an AXMC in 300NM, and I do handload, but I also like the option to be able to shoot factory ammo if it's decent. Hornady 300PRC 225 ELD Match ammo is less than half the price of Berger 300NM 230 OTM Tactical Match ammo, and on my home range of 1626 yds the PRC can hold its own against the NM (but not at longer distances).

It sucks you're having that problem. I shot a ton of the factory Hornady 225 out of mine without a single problem. I only quit using it when they had to change their powder after Covid shortages forced them to, and the ES/SD became almost unusable for the distance I was shooting it. I've never shot any factory Berger PRC, but I now load for it using Lapua brass, Berger 230 OTM Tacticals, 215M primers, and Retumbo. Has been waaaay better than the Hornady 225 ELD load.

Does Berger actually make a 215gr load for 300PRC? I've only ever seen the 245gr Elite Hunter load.
Click to expand...
Yes

215 grain Hybrid Target. Just ordered 100 rounds. I am keeping my fingers crossed that it is better behaved than the Hornady.

I will also pick 20 random rounds of the Hornady to see if the issue is consistent across the entire case that I bought.

My AXSR 37 XC barrel is finally up and running after a 2 year wait.. almost 1 year waiting on the Bartlein modBB blank, shipped 2 blanks halfway across the country only to have them sit at a smiths for a year, ended up having them shipped back to me.. $150 wasted in shipping cost 😡…..

Than hand delivered my blank to Greg at SPR aka Bugholes along with my JGS custom 37XC CEB reamer. SPR crew knocked this barrel out of the park. 4 week turn around time.. Huge shout out to Greg/Russ @ Bugholes..
