I'll bite when I can get it in a mini action. Hoping that Vudoo delivers there because the market has mostly been abandoned, excepting CZ and Howa. I'd kill for a Tikka mini action in this, .223, etc, etc.
I don't see the point on a SA when you have so many choices in the 6mm space. Its more efficient? Great.

Right?!?
Market is wide open for an innovative mini-action for 6.5 Grendel, 6mm ARC, 22 ARC, 223 Rem, 224 Valkyrie, etc. — any AR15 cartridge should also have a place in a modern mini bolt action.
At SHOT Show 2023 I pitched a mini-action Solus to Kirk of Aero Precision and he said he loved the concept, but, obviously, they had to work on rolling out the short-action Solus models first.
Somebody's got to do this project and do it right. Howa's mini-actions seems a little dated and CZ's a little odd.
Mini-action Tikka T3X or Aero Precision Solus would be about perfect. Solus, with it's interchangeable bolt heads would probably be the way to go.
Pretty happy with Gap15 6arc.

Excellent, the 6 mm ARC can be very accurate in an AR, learn to hand load and usually get even better groups, tailored to your barrel.
I recently put together a 6 arc for a dedicated coyote rifle. I wanted something that I could get the full potential out of the clip on I run. Kept getting runners or losing dogs with a 223 past 400 yards at night.
Ended up doing a 18" proof on a simple DD upper and lower with a Noveske 16.7" rail.
JP enhanced BCG and silent capture spring.
I wouldn't say I'm disappointed in it. It's anchored coyotes out to 650 at night for me so far, running serria 90 TGKs. I'll take that as a win.
One thing I will say is i am surprised at how slow it is.
I think part of this is the reduced case capacity on new starline brass. I've tried Leverevolution, cfe, varget, staball match, AA2520, 4895.
LVR was the fastest but ES were insane.(2830) 30 on the low side 60 on the high side. I was able to get 31 grains in there but it was compressed(virgin brass). Still no signs of pressure so I ended up looking at faster powders.
4895 was the best ES/SD and groups but it was slow before pressure. 2600 ish.
Working through AA2520 right now. Seems to be be a good contender so far. ES are good, all under .5MOA easy. 30.1 was (2720)
I have some fired brass that I'm headed to shoot tomorrow. I was able to get 30.5 in the virgin brass before it was compressed. Fired fits 31.5 before it compresses. Going to run a pressure test up to that and see where it pressures out at.

Update. Still didnt even come close to pressure on new brass before I ran out of capacity with aa2520. Numbers look promising. Some groups are okay. I think a seating depth test could help with this powder.
29.7 still looks like a solid contender even though its a little slower.
30.2 is a great group but I don't like the groups on either side of it...
30.5 has good numbers and good speeds with no pressure signs still.

My only regret with it is going with 16" barrel and that's barely a regret. It's more of a curiosity causer than anything. Considering you can get consistent hits at 1k with the 16, it makes me curious at how much better a 20" would be.
As far as the 6 vs the 22, I see people saying that the 22 is a 6 killer but it's going to depend on your application.
The 22 isn't going to reach out as far as well as the 6 does.
7 or 8 shots with a 95g Berger VLD in front of Lever at 100m from a stock Seekins DMR. Been really happy with it, same drift as a Berger 185 Jugg with way less drop and less energy obviously.
Here is my thought. And someone could tell me I am an idiot and they would be right. In fact, my first post here as an introduction, I said I would be the stupidest person here.
So far, I have lived up to that claim.
Anyway, I am reminded of the scene from "Days of Thunder" where Robert Duvall's character talks to the car and outlines the adjustments that will be made. Each race track has idosyncracies that must be dealt with. For example, a slight drop coming out of turn 4, or something like that. So, they can adjust the alignment and camber. Even the tightness of the suspension. Different tires on different wheels. All to make the car really grip the track and turn left a bunch of times.
In that same vein, can one have different loads depending on the job, specifically by distance? One combo works great to maybe 500 yards. But is maybe too light to do well at a thousand. Then, you choose different slug weights, maybe even slug styles, and then, of course, different seating depths, different powders in different amounts.
Anyway, just spit-ballling. What I know about reloading will not fill a sewing thimble your tiny grandma uses.
People do it all time. Different loads for different applications, the right tool for the job. You're not going to use the same loading for hunting at 500 as you would for ringing steel at 1k. Could you work up a load for ringing steel at 1k that is also good for hunting at 500? Sure, but it's kinda like running all season tires instead of dedicated summer/winter setups.
Thanks. Reminds me of a friend who was from Saginaw, Michigan (RIP.) When he lived up there, it was common to have two sets of tires, or at least tire chains. He would have a set of winter tires that he put on in November and they stayed on until April. Then he had the summer set.
Anyway, I kind of feel that way, too. My hunting cartridge is an ELD-X. If I wanted to do long range target shooting, I might change to an ELD-M. I know people are getting game animals with ELD-M. And might win a contest with an ELD-X.
Need to be careful with that. Target bullets and hunting bullets are engineered differently.
AA2520 was absolutely the worst powder I had tried in my 6mmART40 over a decade ago. Why?? its because the temp sensitivity is enormous and so much so when winter came I thought my scope had broke.
On top of that if you work up a warm load in the winter it'll likely be over pressure in the summer and then you run the risk of lug failure in your nice AR.
I'm about out of H4895 but because its so hard to get and expensive I'm going to try Stabal match or N140/50 as a start. At least hopefully some semblance of temp stability.
Edit, IMO velocity is a secondary priority but precision with low ES is top priority.
Debated 22 arc and 6 arc for over a month now. Recently figured I can load down to 58 vmax to do what the 22 arc does or 108’s to do a little more. Everything is ordered decision made 6 arc it is for now. 3-4.5 month wait on receiver’s though, so a little wait.
I bought a Seekins 18” 6ARC and after an initial 60 rounds to test some ammo types and get some rounds through it I’m not disappointed so far.
I gave the barrel a light cleaning before shooting it since Seekins shoots a few rounds to tune the gas systems and basically called that the break in. After one sighter I shot a 5 shot group with Hornady black that 3 rounds went through one hole and then two rounds went on both sides but still touching around 1/2moa ish. It also shot great with ELDX but ELDM was around 1MOA.
All but the first 6 rounds were fired suppressed with my TBAC Ultra 7 with no tuning of the gas system and I didn’t find it to be gassy at all. There was very little blow back. I also didn’t find it to be any more dirty than shooting a suppressed 223 with good ammo.
I’ve got a case of ELDX to go stretch it out to distance next week. If that goes as well as I’m hoping it does I’ll be ordering more ammo and also a proof CF barrel to put on my Larue MGU for a lighter weight hunting setup.

I own a 6mm ARC bolt gun and don't regret it one bit (see below). Matter of fact I love the precision! That said I will most definitely have an upper built for the 22 ARC, no doubt! Will probably have Precision Firearms build me a Neptune MOD8.
My best 3-shot groups with the 6mm ARC at 106 yards this last Friday WITH - Factory Ammo - (1/4 MOA target). Gotta love those Mean Radius #'s:

And, again, though I am sure I have mentioned in this thread before, I saw Kyle at Social Regressive (on YouTube) add stuff to a 6 ARC from CMMG with the express purpose of making it a truck gun for everything from varmints and predators up to whitetail deer. About the only rifle he has not put in a Boyd's because it is an AR-15 platform.
Thanks for the info. I went to the Hornady site and read everything already posted for V/T ammo. What you say is true, including your "mostly" qualifier
. As far as I can read, the new "cleaner burning temperature stable" powders are for the lighter bullets only. Heavier bullets apparently don't get those powders.This makes sense because it all comes down to case volume vs. powder density. The ARC family uses small cases/less volume. This is not an issue with lighter bullets which move down the barrel faster, so faster burning, denser and cleaner powders will work.
But that doesn't seem the case with heavy for caliber bullets, maybe because they need slower burning high density powders and there are not many of those in the market, and the ones out there are not very clean powders.
There is hope that now that this small cartridge/ big bullet paradigm is catching on powder manufacturers will come out with a solution for the "cleaner" issue while making a slower burning high density powder that will work with the heavier bullets. StaBall Match might just work, but is it cleaner?
Here's the quotes for the 22 ARC 62 grain V/T - similar with the 100gr V/T for the 6 ARC:
"Modern, clean burning Propellants
Carefully chosen for their consistency no matter the temperature, you can shoot with confidence, knowing that every trigger pull will be met with the same exceptional performance, whether you’re competing in the heat of summer or varmint hunting in the chill of winter."
And here is what is say for the 22 ARC 88gr ELD Match:
"Carefully Matched Powder
Powder is matched carefully to each specific load for optimal pressure, velocity and consistent accuracy."
When I read I also pay attention to what "is not" written...

Yeah so the case volume on the ARC/Grendel sized cartridges doesn't lend itself to great velocity numbers with extruded powders. Traditionally the extruded stuff (ADI/Hodgdon Extreme, newer RL series, etc.) is what is the bee's knees for consistency and temp stability. However, pound for pound you can get exceptional velocity with some of the ball powders available. Packing efficiency among other things gets better with larger case volumes and the velocity gap between extruded/ball shrinks in the larger cases. We've been working back and forth with powder suppliers to get powders/blends that fit the case capacities for the 6mm ARC very well over the last couple of years. The original blends were pretty sooty but we've got a newer powder that is quite a bit cleaner burning with the same velocity/accuracy performance that will be going into the 103-108gr class 6mm ARC and it works well for the 88gr 22 ARC, too. Both of those powders are good for temps *for ball powder*, but sorta "meh" compared to modern extruded. On par with stuff like the old IMR lines. The V-match 62's and 80's (22 & 6mm respectively) can take advantage of some powders in the new Sta Ball HD series that are both very clean and very temp stable.
With supply chains the way they have been the last few years I can't guarantee anything going into the future, unfortunately. When we have Varget, H4350, temp stable ball powder, etc... We load it. When we don't, it's a game of compromises and the choice ultimately comes down to "don't load X ammo, or use substitute B,C,D powder", and for the most part the customer prefers to have something vs. nothing... The age-old crux of buying factory loaded ammo, it's subject to change components lot-to-lot and you don't know what they are or how they'll perform until you try them.

FWIW I just cleaned my 6 ARC. Only the first 60 rounds of shooting suppressed but I didn’t think it was overly dirty at all. If anything I’d say it was on the cleaner end of what I typically see shooting gassers suppressed. I’ve shot less rounds through 223’s suppressed that had way more carbon in the BCG and receivers.
I only cleaned the barrel since it seemed like it could have been fouling up a little and accuracy was falling off towards the end testing the 3 different ammo types but left the action as is to see what it would be like after a few hundred rounds. Going to a 2000yd range tomorrow with a case of ELDX and a couple more boxes of black and ELDM to see how it does at distance.

When do you think the V-match might start hitting shelves? I’d like to get a couple cases to try out.
Thanks again so much! That is very much need to know for me as I don't reload anymore, I did it so much it felt exactly like work!
Plus, The 108 ELD factory stuff shoots lights out on my 6 ARC bolt gun. Most precise rifle/ammo combo I own. I'm on my 7th case of 108 ELDs.... Average velocities in the mid to high 2700s - Until a certain Lot# showed up.
I had my suspicions about that before you just told us how it all works when I started seeing different color primers in different Lots. My suspicions were confirmed recently when I got the new Garmin to replace my Magneto Speed. I pulled out a couple of boxes to test the Garmin and I started seeing velocities in the high 26 to low 2700s, about a 60fps difference. My first thought was about the Garmin "crap! I got a dud!)
Next time I took the magneto speed and the Garmin out for comparison and confirmed that it was the ammo lot. Still shoots great at 100 yards but now I will test all my lots when I start shooting them. This because I shoot long range as well and for the zero range on the 4DOF app to work I need a valid average velocity...
Thanks again!
What load are you shooting? I just got recent lots of all 3 and the Black and ELDX cut little knots like that picture but the ELDM was .9XX for the best group and 1.1-1.2 for the other 3.
I would love a temp stable ball powder for Grendel/ARC. My go to is 2520 but it's temp instability necessitates loads for different ambient temps and load data for seasons. It's not that hard but you have to pay attention and it would be better not to have to.
Or you could just put the powder temp variation in your ballistic app and it will automatically do it for you…
I've worked up 223 & 308 loads for gasser and bolt comparing AA2520 to Staball Match. 77gr 223 they are almost dead even & both hit pressure within .1 - .2 grain apart (slight edge to Match). With heavies like 85 RDF or 88 eldm the Staball match starts pulling ahead of 2520 for speed at any given gr charge. Still hit pressure at damn near same charge, but Match is delivering more fps. For 308 again very close with 169 & with 177 Match starts to show more speed per gr.
Staball match isn't in GRT or Quickload. I've just substituted 2520 to find starting charges for Match.
When I get my hands on the 6mm 80gr VT's I'll be trying Match in the 6ARC for sure.
Shooting 224V next weekend with the 62 VT's comparing Lever, XBR, & Match

I’ve lived in FL a whopping 4 years of my life and have used Kestrels and iPhones in below freezing temps plenty. Shit can fail in the heat just as well as the cold.
Regardless of your method of getting dope it’s still easier to carry around range cards for one solid load at different temps if you’re not experienced enough to add or subtract drop based on temps going up. It’s a hell of a lot easier than having different loads for different temperatures that will shoot entirely differently. That’s just retarded.
I bet he leaves it on the ground for the peasants to fight over like a G.
Nope. They all go back in the box
And from the bolt gun they are all pristine. No soot on the outside except for a quarter of a way down the neck or less....
Nope. They all go back in the box.
Yeah mine aren’t clean at all but that’s gas gun life. The soot is about the same as a long gas system 223 shooting quality ammo which I don’t find to be bad.
The ammo is running but there were delays in like labeling or something? I'm not exactly sure, not my department. I'd imagine it's a matter of a week or three before you see it on shelves, but that's just my guess.
Grabbed an 18" Proof that was in stock today and hope to have it by the end of the week. Seems like magazines are the weak like at the moment so hopefully that is rectified before too long. I've got a Duramag and ASC mag on the way.
Looking forward to seeing how it shoots the 108's, and will very likely shoot mostly 80's when they become available (but keep 108's on hand for long range stuff).
Excited and will keep everyone in the loop! Thanks for the info so far everyone

Good to know thanks! Was wondering why 6mm ARC 108s were going on back order (again) with the people I buy it from. I ordered two more cases today from another supplier just in case
. Question, can I use my 6mm ARC mags with the 22 ARC?Looking forward to testing the 80 grain V/Ts on my bolt gun!

Yeah ARC/Grendel magazines should be pretty interchangeable.
What’s everyone running for a buffer / spring?
I’ve got an 18” Proof with rifle +1 coming and an adjustable gas block. Unless there’s a reason to do something different, I’ll probably run an H2 buffer and carbine spring.
ETA, will be suppressed most of the time

Wouldnt call it regret quite yet, but my proof barrel is on the way back to them for diagnosis, as it was shooting 1.5"-2" groups with hornady black and hornady eld match.
Jumped on the proof bandwagon, and now wondering if I should have just waited it out for one of the shops like CLE to spin me up one instead.
Second proof barrel I own, and I wouldnt exactly call the first one above-average either..

Are they Proof Carbon fiber or SS barrels. I purchased 3 of Proof Researchs SS barrels for 2 for 6 ARC & 1 for 308 in AR platform...they can shoot 1/4" 5 shot groups, .3s to .4s common for 5 shots with the SS barrels...I wouldn't buy a carbon fiber barrel, unless I was building a walk around hunting rifle. I infact built a 6 lb 3 oz AR 10, in 308 without going to carbon fiber barrel or a pencil barrel, but a fluted SS barrel...and it's shooting .5 to .7 inch 5 shot groups with 169 gr and 177 gr SMK...with 3 shots 1/4" good for a thin SS fluted barrel. I've had excellent SS barrels from Proof, hope their quality isn't slipping.
This is part of what I do to make my Proof Research 6mm ARC barrels shoot 5 shot 1/2" groups, or less. Notice this reciever was out of square, center the bolt carrier, glue in with high temp green bearing sleeve loctite. Wax reciever where barrel extension slips in for easier removal of barrel. Tighten barrel nut to 60 ft/lbs, mill slot in barrel for gas tube if necessary, but do not over tighten. Some like 48 ft /lbs. I perfer 55 to 60 ft lbs...maybe this will help, with Proof barrel inaccuracies in AR platform.

I went out the JTAC yesterday with @Mike Casselton and shot it as far as 1200 yards with the ARC. If I had more 108 ELDM’s I would have stretched it further and I bet it would have smacked 1500. I only had one box of ELDM left (only bought 2 to try) and shot it at 400, 800, 1000, and 1200. I went 3/3 at 1200 on annd IPSC (not sure what size) and had 2 hits on a 4” plate at 800 with switching wind so needless to say I was pretty impressed, especially doing it with factory ammo. Assuming the .9-1.1” groups at 100 with the ELDM load the other day wasn’t just a fouled new barrel (entirely possible and pretty likely) I don’t know why they were shooting so well at distance but they were. It was much more consistent than the ELDX and Black and distance both of which shot knots at 100. The 105gr Black shot like ass beyond 400 yards.
The ELDX was pretty much automatic to 800 and it was easy to self spot misses and hits to that distance. At first it kinda sucked beyond 800 yards and I couldn’t get a hit on the 4” at 800… until I took my can off. I don’t know why it started shooting better beyond 800 after that, but it did. Maybe the barrel sped up since I was about 180-200 rounds in at that point and SD’s tightened, maybe it was harmonics, I don’t know. I had 60 rounds of ELDX left I had found in my bag after shooting my 223 so I swapped the optic back over and it was much more consistent at 800+. I got several hits on the 4” at 800and was laying hate consistently on the IPSC at 1000. Sometimes semi rapidish fire. I don’t recall if I tried 1200 again with the ELDX’s or not.
I brought my 223 too which is the identical Seekins rifle (18” DMR) with 100ish rounds of the varget 77gr SMK loads I loaded years ago for another rifle and 40 rounds of Norma. There was a significant difference in how much easier it is to spot hits and misses with the ARC even at 400 yards. I had to swap optics and did a dirty zero on a partial size IPSC at 200 and went to 400, 800, and then 1000. I couldn’t see the 500 and 600 from where I was shooting. My second shot at 800 smacked the 4” and I hit it one or too more times. I went to 1000 and went 4/5 on the IPSC there. The load is subsonic around 850 or so. I tried the 77gr Norma and couldn’t hit shit beyond 400. Not sure what was going on but it was ass.
I didn’t notice any difference in the ARC pushing me off target after a shot than the 223, I call it a wash. I’d even call hit ratio out to 1000 yards basically a wash. The main difference out to 1000 was just how much harder the ARC hits the plate making it easier to call hits and how much more earth it kicks up on a miss.
All in all I was very impressed by its performance and it’s the first Grendel based rifle I’ve had that hasn’t been disappointment. I need to get some more ELDM and do some testing but I’d say this rifle is here to stay. These Seekins rifles are stupid accurate and a value for what they cost.

Thank you. I appreciate the advice.
In this recent case, I used a VLTOR MUR upper. I did not lap the receiver face, at the advice of Chad from SOTAR who told me that if the lapping tool had any resistance inside the upper, it shouldn’t be used as it may risk removing material from the upper interior. In lieu of that, I followed the Joe Carlos method…using steel shim and green loctite to bed the barrel to the upper, then torque wrench install for the barrel nut, muzzle device, etc.
My other proof is significantly better in performance than this one (just not significantly more impressive than other barrels I own that cost a good amount less), however the barrel extension to receiver fit was similarly sloppy…different brand receiver, and I used permatax Indian head gasket shellac (at proof’s advice) to bed the barrel to the upper.
I gotta chime in on Christensen too.
I bought an MPR 300 WM in March 2022 from Eurooptic. They were offering a rebate (which I never received...), and the rifle was $2200. I picked it up at my FFL and immediately disliked it. The bolt was so loose and gritty that if you applied ANY side load whatsoever trying to move it forward from full rear position it would lock up on you completely. You'd have to wiggle it like your worn out key trying to get your house deadbolt to unlock.
I took it home, and let it sit for a month before deciding there's no way I can keep it, and I didn't want to have to send a brand new $2k+ rifle back to get repairs. Never even bothered to scope or shoot it. Sure looked nice though. And the balance was good, but that's about it.
Personally I will never bother to purchase from them again over that experience. And since then, I've been more aware of comments made about Christensen, and they're all pretty awful. I'm surprised they're still in business 2bh...
