id just get a proof prefit barreled action from altus then (or anywhere else who carries both)
I know Keystone has about 20-25 Green Mountain blanks left from the 50 they received not that long ago. Believe they are under $400, custom machined to your spec/contour and turn around time is days, not weeks or months.
I actually just received one from this new batch yesterday and put about 200rd through it to get it broken in and it is looking nice. There was zero feeding issues, ran amazing. Gonna take it out again today and shoot some 6x or 10x. Ill post up some results later.
My other 2 GM's shot lights out and in my RimX barrel review... If you dont already have a Bartlein or Krieger in hand, this may be your best bet for getting a custom barrel to your exact specs in a reasonable timeframe at a cost that doesnt break the bank. I personally think these 22LR Green Mountains are the best value RimX barrel out there. The Krieger and Bartlein are the cream of the crop in my barrel testing, but the GM was the 3rd best and not that far behind. The GM shot the smallest single 5 shot group of all the barrels test at both 50yd and 100yd also. Talked to Frank @ Bartlein the other day, your looking at a LONG wait, things are just more insane then ever before right now.

Thanks for the feedback. I've been following your testing since the start. Keystone is definitely on my list of top considerations. I'm not fooling myself and thinking that this will get me from mid pack to podium. I just want a really nice rimfire that is accurate, feeds reliably and balances nicely while I'm out making an ass out of myself in the MARS / NRL22x / PRS rimfire matches.
Edit to add - I realize I could get something cheaper (Bergara, CZ, Tikka etc). This is 100% a "I want something super nice" purchase and I only plan on doing it once.

I have a keystone barreled action right now. I have another from Desert Precision on the way. My brother is buying my Keystone because he loves it so much. I don’t think you can go wrong with any of your choices honestly. I went with a 22” 1.2” straight contour barrel so it balances better in my chassis.
I would also throw PVA into the mix for a good barrel.
I am in your area with the tools to put it together can help you with setting up your mag height if you want. I think the mag height is almost more critical than a prefit barrel installation for feeding
PVA is out of stock on both barrels right now. I thought about going with their 12 twist as I know you and a couple of others have had good success with them.
Proof prefit is a pretty easy install and feeds well but their chamber is pretty loose and it doesn't shoot the tighter groups compared to the custom chambers at Keystone and Desert Precision
I have both a 22 inch PVA 12T and 18 inch Proof Comp Contour and agree with the above. Personally the PVA to me would be worth waiting for.
I appreciate the feedback. I have a PVA John Hancock Rifle and love it.
You all aren't making this any easier on me.
What chassis or stock are you planning on using? If you are thinking of the ACC, you may want to go up to a 22 inch long barrel.

Got this new Keystone Accuracy Green Mountain back out today to really see how it shot with various types and lots of ammo after breaking it in yesterday. Good old 22LR, ammo and lot testing is the name of the game. 
After putting 200rd+ through it yesterday, then giving it a cleaning today I went to the range to shoot some groups and test ammo to see what it liked. Upon arriving at the range I put a 50rd box of SK Pistol match through it to foul the barrel then started the below ammo test. It really shined when it found ammo it liked but thats the name of the game with precision 22LR isnt it??
Here are the results if you dont want to zoom in and read the target
Everything was shot from left to right, starting at the bottom and going up. All groups were measured with calipers outside to outside black smudge minus .223. If you subtract something else, go ahead and +/- from my recorded group size. Ive used this method and measurement for all my testing so Ill stay consistent for comparison sake.
Two of the CenterX lots were straight hammering. Cant wait to get a calm sunny day to shoot them at 100yd! Those 2 lots shot sub 0.5moa 10x5's which is awesome. I dont think you can find a better value for the money. Custom made to your spec RimX barrel sub $400... Hard to beat that. Is it the MOST accurate RimX barrel, no. Did it shoot the smallest groups or AGG in all my 22LR testing, no. But it sure does shoot consistently for the money and brings a ton of value with the right ammo/lot!
Also, this barrel is not using my chamber. This is a new custom .22LR Match reamer Keystone Accuracy had made a few months back that they are using for all their RimX barrels unless someone specifically requests a different reamer. So far, just over 200rd down it yesterday and 550rd down it today. Not single feeding, ejection or stuck case issue. No shaved lead. Ran like a swiss watch.
Shot from the bench at 50yd, bipod and rear bag. No can.

Thanks for all the effort you are putting in testing these barrels and ammo
Brand new one received this week with Keystones new match chamber.
Which barrel shoots better the first one or this one ? Just Curious
I think they both shoot really damn good for the cost.
After a quick zero check at 50 yard. Wifey drilled this 3 round group at 200 yards with Eley Pistol Match. And then a 10 round group at 150. Light winds 9 o’clock 2-3 mph. She used to do even a bit better with a trigger tech Diamond but since it’s her “trainer” I put a TT 2 stage because that’s what she has on her Arc Nucleus 6.5cm so the pull went from 8 oz to 1.25 lbs.

I feel like I forgot to order a piece. I can't put my finger on it though ..
I have mine in a Manners t2a gap stock!! Im sure it will be good to go in PRS stock!!
Any of you guys looking to trade a 40MOA base for a 30MOA?
My Midas Tac can’t quite make it to 400yards with the 30MOA base.
My Midas Tac can’t quite make it to 400yards with the 30MOA base.
I know a guy who uses the Burris bushing rings to make it to 500 yards with his T1X...
That could be an alternative to swapping base.
I use 30 moa on the base and I can make it to 400 (barely) with my Athlon Cronus with Eley Match at 1111fps on a hot day.
That’s not a bad idea. I probably don’t need to get to 500 though. We’re running a PRS Rimfire match this weekend out here at The Lead Farm and the most we’ll push the 22 targets is 400 or less
That’s only hearsay because I don’t know anything about those Burris bushing rings but it was explained to me that with those rings once you figure out the right insert, you could set it up to zero almost at the end of the travel limit on your scope therefore maximizing the available elevation on your scope.
Also, some scopes you do get a bit more travel when you remove the zero stop and for example, on my Cronus with 30moa base, I don’t need the zero stop because at 10 mins per travel, I’ll never be going more than a full turn.
Food for thoughts
I feel like I forgot to order a piece. I can't put my finger on it though ..
Where are you ordering a barrel from? I'm considering a WSM also.
i run a 40moa base and 20moa M-Brace with a Razor G2 or Strike Eagle
Contact Zermatt. They will usually trade.
I thought about that, but I’ve had this rail for a year or so now, so they probably won’t want to trade a used one out
This showed up today. Plan to spin it on tonight and take it for a test drive this weekend. 
Is that a new barrel or you picked it up used?? That breach face looks roughhhhh. Yikes.
I'm not sure if its that rough or just the way my camera took the pictures at the angle it was on. I swabbed it with a Q tip and nothing snagged. I was thinking the same thing when I took the cap of.
If it don't Di Precision knows I bought it and who I bought it from. They were trying to help him sell it as well. Worst case the PVA goes back on and I send it to them for corrective action.
Looking forward to the results
A thin piece of kidex on the breach face below the action wrench makes me feel better when spinning a barrel off & on. Textured side is up and slick side is down.

To be honest, you should leave the ejector in the receiver when you use the action wrench and just stop when the wrench hits the ejector. It will have more lug engagement and torque will be absorbed better by the receiver.
Being that far away from the threads is acceptable since there is considerably less torque required in this area.
Thanks - Ray
Thanks. Ray. I was afraid I would screw up the ejector some how. I will not remove it next time.
@Zermatt Arms - Ray does that apply when removing a barrel as well and what is your minimum recommended torque?
I finally was able to find some time to shoot the RimX at my dads farm. This rifle is so fun to shoot. The action is so smooth and feeding is flawless. Shot 250 rounds today of RWS Rifle match without incident. Here is the targets for sighting it in and getting use to the rifle. I spent the rest of the time shooting my KYL target at 50 and 75 yards. Only missed a handful which for me is outstanding. All the groups are 5 shot groups shot at 50 yards. Didn’t measure them but I was happy with them.

I was able to shoot my New to me Di Precision built Kreier 22" 16T with EC Tuner on Saturday. I am shooting a lot of SK Long Range that I had 1900 rounds of. I was happy with the Tune test and need to stretch it out to 100 for a fine adjust. All in all I think its a great barrel and I will be shooting it for the next few matches. 
Get a Vudoo it will shoot better. Your groups suck
….ok. Haven’t been shooting since July due to the death of my father and not really trying to get the absolute smallest groups I was ok with them. The rifle is more than capable of shooting much better. But you have a good day.
That’s why I blocked him a long time ago.
Don't let the troll get to you. They've been in and out of this place a few times spewing garbage that certainly doesn't add to the conversation.
It takes all kinds of kinds they say.
More responses like this, and you'll find yourself on vacation. Clear?
If you want to troll, or talk shit, keep it in the pit.
