Depending on the chassis you're using.
With the magpul pro 700 the AW magazine feeds flawlessly and it has enough bolt engagement, without modification.
You might need to adjust the magazine height/feed lip to allow the enough bolt engagement to be able to true CRF.

I was thinking the same thing. The AW mag presents enough of the cartridge to function fine as a push feed, but I think a single center feed mag would be easier to setup for 100% CRF.
Now that AI is focusing more on the comp scene, I wonder if they will release 12 and/or 15 round AW mags?
You can see how the timing on the magazine is crucial to match the cartridge length for CRF. This magazine has had the feed lip shortened so that the lower cartridge presents a bit of the body instead of the neck to push up on the upper cartridge as it clears the feed lip. If the lower neck is presented upward it doesn’t have enough height to push the upper cartridge into the bolt face fully. If the shoulder is presented when the upper cartridge clears the feed lips it will pop the upper cartridge forward faster than up resulting in push feeding.
feeding a 6.5 Creedmoor from a stock ARC magazine. Note the jump forward from the slower shoulder doing the lifting.
I use AW mags... I'm also thinking of buying an AT-X... If I do this to my AW mags would that have an impact on using those same mags with an AT-X.
I'm guessing it wouldn't be a problem, but I'd like to know before I do anything permanent.
Thanks!

TL3 in 6mm ARC with manners PRS TCS. And mark 5hd 5-25x56 used for PRS type shooting
I got me 7th in the place of the last match pushing a 105 VDL at 2920 and a sd of 7.5 loaded on a dillon 750 with a dillon powder drop
not quite my 6mm GT but works

No but it didn't hurt 7 months of practice and competition got me there but it didn't hold me back
My GT has more speed lower SD's with a 112gr match burner. But I use a autotrickler and single stage press. It's nice to be able to load good Precision Ammo as fast as I can with the Dillon 750
Wow that's awesome what powder do you use in your dillon to get low SD in those. The only power that works will in my dillon is a ball powder and my gt likes running Varget.

What will an BR do that a ARC won't do? Why go through the exta money in brass and no off the shelf ammo or very limited ammo. We can all say that it not right or worg just different. BR, BRA, Dasher, GT. Creedmoor, 243. All great and all will push a 6mm bullet.
I wonder if it performed the task you bought it to do. Sometimes if you commute to work it doesn't matter if you drive a PT Cruiser or Maserati you'll still get to work
I don't know but feeds great out of a mdt .224 Valkyrie magazine. Check it out someday. God bless you have a great day. Thanks for the inspiration. 
Jesus! I have read your posts @reubenski here and there for quite a while on the hide, and there has been some useful, even helpful information. But good lord let the man shoot whatever he wants to shoot. Why the fuck does it matter to you that he shoots an ARC?! Take the pissing match to PMs if you want to change his mind. The rest of us read this thread to discuss TL3s, not to get your opinion on whether someone should be allowed to run a certain cartridge or not.
That is an awesome rig... Even in 6ARC!
To be honest, if I were starting over today, that's exactly how I would set mine up. I have an early stainless model TL3, but I much prefer the black, I have a T6A, but the PRS-TCS wasn't available back then, otherwise I would have bought that.
Anyway, I've been thinking about shooting 6ARC in my TL3, just because I'd like to setup one of my ARs for 6ARC and at that point, I don't think it makes sense to have both a 6 ARC and a 6Dasher. The only think keeping me from making the jump is powder, I don't have any powder suitable for 6 ARC.
I've ordered custom bolt knobs from the Polished Knob out of Montana. You can find them on Facebook. They made one for my older TL3 as well as a newer thread version too. Zermatt should be able to sell you replacement bolt handles with either thread pitch as well.
Yes, no. The brand of magazine doesn’t matter here, the ARC mag JUST comes standard with shorter feed lios than factory AICS magazines. ALL feed lips need to pair with cartridge length for CRFing. Shorter feed lips will CRF more (longer) cartridges than longer lips but too short of feeding lips and you may find stability isdues where the cartridges will want to escape out the front 2/3 (or whatever) under impact. This trim to properly fit the cartridge bring used.
I have two TL3 actions and never an issue with any mag. No cutting needed.
I did say it wouldn’t be reliable, I am glad you are happy with your set as am I. Most people aren’t aware they aren’t ACTUALLY controlling the round when feeding and many say to run the bolt fast to get it to crf but this is an attempt to overcome poor timing of the magazine.
Would be interested to see video of the slow operation of your magazine/cartridge combo setups that work for you if you would be willing to share.
Do they PUSH feed fine or are they actually fully controlled while fed? The TL3 push feeds very reliably too.
Took my TL3 chambered in 22-250 AI out for a spin in WY this weekend - it's shooting very well with the 88 gr ELDMs and RL-23. Smoked a coyote at 600 yards Friday evening and then shot my buck at 315 yards the next morning. The TL3 just continues to impress!

How my TL3 currently sits. Mostly used for hunting, but sometimes I'll put it in a chassis for local matches.

Range and load development I run sleds from CNC Werks. Will also let you know if your TL3 is AI cut the AICS/CS sled will need modified and CNCSWERKS can make it happen, just let them know when ordering. The sled they offer for AW requires no additional mods. Hope this helps.

Runs good magazine fed. There are couple magazine options. Accurate 300wsm mag, Hawkins 3rnd mag and maybe few others.
If your Origin is cut with standard 700 feedlips I would say yes on the modified CS sled. I fit up a Remington 700 SA this morning and the AW sled is to long and would not seat. The pictures are of the CS/700 SA.
