Think Bjay meant ARC, but these are about as reliable as you can get for that combo:

Thats me though I’m patient. Since i got into the custom rifle game every time i try to attempt a short cut or get something faster it always has backfired . I presume it’s my luck at this point
If you call that a "benefit" then yes.
Some say the extra space that could be less accurate than ideal so not a benefit, some say it is a benefit so that they dont get themselves shot in the head while fucking with sand or an oversize case.
The armed forces call it a benefit because its all factory ammo and every round can get chambered and fired with no fuss.
Reloaders dont think of it as a benefit because, as you said, after the first firing the extra "beneficial" space is gone unless you are over working the brass to return it to virgin specs on every firing. Then that benefit comes at the cost of reduced case life.
Same holds true with any action though, not just ai. After the first firing on the brass 5rwill can just bump the fired shoulders back a skosh and reload as usual. Doesnt mean its how it was meant to be though. Some better measurements from him or his smith will provide more info into where the difference actually is.

Thanks for the information and link....new to this type of set-up, so another question - with or without binder plate?
Thanks for you help!
I'd say without .
Guys that are removing binder plates( or are using Accuracy International variants that are sans plate) are doing so because they are running cartridges that pushing the limits of the Cartridge Overall length that will fit into a magazine and feed properly.
I don't know what bullet you are using in the 6.5creedmoor (likely factory configured) ammo, but it likely will not push the limits of the magazine internal limits.

Planning on handloading sooner rather than later....I would rather have the flexibility in overall length as long as reliability is comparable.
Thanks again for your help!
Impact w/ AW cut in the vids
AW mag...bottom metal set so mag follower rubs the front of the bolt nose with no rounds loaded
AICS mag supporting the rifle by the mag...bolt rubs the mag lips, but doesn’t bind

Waste of video but one sec lol
The AW is set so the mag feed lips hug the bottom of the action cut...it doesn’t touch the bolt at all

I’ve been runnin the AW cut with AWs since last December...love it, have another one being cut right now
AICS mags are the easy button, but AWs are money once you set it all up right

That’s how I did this one...my new one I asked Tate to cut it before sending it to me...he was runnin a batch of them soon, not sure if he’s already finished them or not
Just be aware you’ll have to adjust the mag height for it to run reliably...either by extending the mag catch or recessing the bottom metal deeper
The one time i tried an AW cut with a 2-lug it was weird. Granted i did't adjust the mag depth at all and dropped my TL3 into a mini-chassis cut for my Tempest. Just always heard the old adage that it could be problematic to run a 2-lug with AW mags because of the smaller diameter bolt body and less surface area for purchase of the casing. Having said that i think running a 3-lug with anything but a double stack mag like an AW is disingenuous.
Morgan that video looked pretty dang smooth though.

Yea, I’ve ran this same barreled action in an AIAT chassis, an MPA chassis, and now it’s in this Foundation...dropped in with no mods it wouldn’t run AW mags in any of them reliably
After mods and setup tho, it’s been 100% in all of them...ran it in the Brawl this year @ RO and even with all the mag changes, no issues there

How did you get yours set up right ? I recall you said last year you’d never go the AW route with a 2-lug UNLESS you know what your doing to get the mag working just right...so what are you doing ? Thx
with the MPA and AT chassis, i just welded up the mag catches and reground them back to the right height so the mag hugs the bottom of the action
on the Foundation, because of the way the Hawkins bottom metal is designed, that doesnt work...so we just cut the DBM inlet like .045-.050 deeper so that the mag hugged the action the same way
ive only run AWs (with a 2 lug) with my Impact...i havent tried it with any other 2 lug actions so idk how the bottom of them are cut, and if you can get the mag up high enough or not...but with the impact it has worked great. you basically have to be able to get the mag up high enough that the bolt nose hits the follower with no rounds loaded, similar to the AT/AX with AWs

P.s.. I just got that AI back?. Impact action is a kmw is MONEEYYYYY
Does the foundation stock come with a full length ARCA rail on the fore-end, or is it an add-on option?
Comes with anschutz rail.arca is an option. If you buy wothout arca make sure add picatiny rail otherwise you cant use qd bipods for picatiny.just got my exudos
I'm running my first shouldered prefit which came from Impact and its worked great. Last time out with it had a sub quarter MOA 5 shot group with a 6.5CM. I try but don't always shoot that well but I believe the set up is capable of it when I am (not as often as I'd like
I've always loved the look and feel of the KRG Whiskey-3. I just wish they would come up with a forend that has an integrated Arca rail as well as a method for making the chassis heavier. If they did those two things I'd probably order one immediately.
I recently found out that they have a weighted flat bag rider that adds 1.43 lbs and a weighted spacer that will add .66 lbs. They also offer a heavy angled bag rider that would add .9 lbs. Arca rails are also available.

In case anyone was wondering a Bighorn action wrench will NOT work with the Impact. I was pretty upset when I went to torque on my barrel Friday lol
I use nothing but ARC magazines with mine normally, no spacer kits and it still feeds 6BR great.
It does, however, work with a standard Rem700 action wrench.
Is anyone running magazines with no binder plate in these actions in 6.5mm Creemoor? I've got a 737r on order that will be going in a MPA competition chassis, and I'm debating the binder vs. no-binder plate magazines (Accurate brand). I don't want to have to notch feed ramps, but would prefer the longer COAL without binder plate for loading solids. If it's going to come at the expense of reliability for things like 147gr/143gr eld-m/eld-x though, I'll just get the binder magazines. I saw post talking about this:
but that was for 6BR with a spacer kit, and another two that weren't cartridge specific:
Would that indicate with 6.5mm CM it'll be no issue for factory ammunition as well as longer handloads? That's how I'm reading it, but would like to confirm before I buy a bunch of magazines that won't work. Hands-on experience would be awesome! Thanks.

This was his exact response: "With a properly tuned magazine we have had no problem running magnums at lengths that barely fit in the accurate mag without the binder plate.
Thanks
Tate"
I ended up changing directions with the build so I no longer needed the no blinder plate mags.
I was going to build a 7SAW because I wanted something different and was impressed with its reported performance. But I'm impatient and indecisive and didn't want to bother with renting/buying the reamer, getting to a smith, making sure they got it done in time if renting, buying custom dies/brass etc. So I just built another 6mm. I LOVE my BR. It's crazy accurate and so easy to load for. Went with the 6XC so I can shoot the 115gr DTACs.
Tuning magazines just means bending or trimming the feed lips to ensure they don't interfere with the bolt (and they release the round properly), as well as potentially shimming the magazine catch to remove any slop or play in how the magazine inserts into the rifle.
Got my Impact wrench and finally had a day off work to get it put together. Hopefully I'll get to start some load development for it over the weekend.
Finally got mine squared away this weekend
