Accuracy International Picture Thread

Looking good, now get some loads worked up and let us know how it goes!

Is Dave putting flats on the barrel? Looks like something near the muzzle.


More stuff arrived today, including a 27" 300 PRC barrel by Dave Tooley. Hopefully I can get the new AXMC out soon.

Anyone using a SOCOM 7.62-RC on a 300 PRC or 300WM? Thoughts? TIA.

I'm going to catalog the first 100-120rds through the barrel as it speeds up using factory H225s. I'll develop a load using N565 and RL26 for the 220 Bergers and H225s.

Cut with 6 flats.

SOCOM 300 on a 27" TRG .300wm. I bet the RC will have a sharper tone, but is a more durable suppressor than the 300. With a barrel that long, you could probably use most anything.

I keep hearing that AI is not meant to be the most accurate rifle out there. They say that it isn't purpose built to deliver accuracy like a fully custom bolt gun....

I also hear that factory ammo can't compete.

Hmmmm.

This was one of yesterday's results while comparing different ammunition.

This was PRIME 6.5 CM out of my AI AT. It was the best group I shot but the others were all below 0.6MOA at 300 yards. Even the 5 shot groups.

You have to love AI

Who the hell says any of that??? I've never heard it, and never thought AI's were viewed as being inferior to customs in the accuracy department.

I've heard it many times at a number of different places...forums...matches, etc. I never bought it but I have heard it here as well. Look at any of the threads dealing with "should I buy an AI over a blah blah custom". People always state a custom's precision is a reason to go that route.

I have 2 AIs and have never questioned the rifles potential for precision
 
@Nik H Uhm, an AI is a lot harder to shoot off your belly/ bench than a custom gun built for comps... ain't nothing wrong with admitting that. It's not going to make me switch.But I can see why guys favor other rifles vs AI's...

Maybe you should show them what's up at an actual match? Make them believers?? ;)

LOL...I am a non-competitive type. My mental game prevents me from competing in high pressure situations. So I just smile a lot.
 
Hey guys, I need someone with an AX short action rifle to do some fit tests on a couple of items I am printing, I already print items for the AXMC, and AT and they are being tested but need a volunteer to check fit and use the AX prints at the range. You'll get a new set to keep once everything fits and runs right, just need some feedback, disregard the AT on the test items, the originals were printed before I knew there was a difference between the AX and AT mags.

@Mr. F
 
I found out during a test fit that the AT mags do not have a front lug on them, therefore the AX mags will not fit in an AT rifle. Not sure if it will work the other way around though.

Good to know. I don’t have both and always figured they were the same. They do have different part numbers.
 
AT mags will work in a AX.

^ This

AT can't use AX mags...well it can, but only after you hammer in the front tap flush with the side of the mag.

While the AX can use either mag. You can feel the front lug on the AX mag lock into place, but both AT/AX mags still have the exact same amount of rattle movement and feed exactly the same (flawlessly) in my AX.

@pfl338 I don't see any real reason to make the AX specific version

Received mine and hope to have them out tomorrow for testing.

I've a few AI's, well more then a few... :) and willing to test out some of your gear if you're needing guinea pigs.

View attachment 7437739Here is the prototype bag rider, the machined one i made out of 7075, that works fantastic, the printed one( installed on rifle) will need some more mods for it to become viable, but I think I can get there and be able to provide an economical bag rider that functions well and is fairly durable, I will require test beds, (AKA volunteers to abuse the crap out of it to see how durable it will be be.) super light compared to the all Aluminum one.​
 
I got a chance to hit Quantico today to start breaking in the 300 PRC. I got 70rds down the new barrel and will be able to develop a drop chart and take the rifle to 1,000 tomorrow.

I tested the 3-D printed lead sled, safety block and extended mag release for fit and function, absolutely no issues. I also chrono'd each shot so I can track and plot the barrel's speed. I shot factory Hornady 225s (60rds) and 10rds of the Unknown Munitions 220 Bergers over some IMR 7977.

IMG_5262-1618357.jpg


I wasn't necessarily shooting for groups but here are shots 16-20 of the Hornady, I think this Dave Tooley 27" barrel is a shooter as long as I do my part. Speed for the Hornady today was in the 2850 range, but given it was factory, there were some wild variances.

Does anyone here know what height rings are needed when mounting a scope on a AI AT high 20 MOA rail?
AT doesn't have continuous rail so you can get away with low rings; however, I've found them to be too low for the cheek piece even at it's lowest setting. I just put a ARC M10 QD-L at 1.38" height, with the Wiebad cheek pad that is about the minimum height as I have the cheekpiece at it's lowest.
