Let us know how it goes…, been looking for those powders you mention, but they seem to be out of stock everywhereI only just started reloading this cartridge because of this gun so I can't offer a whole lot of help or speak from any real world experience. You are correct that there is not a whole lot of published load data out there, I'm using some data that I found on the five seven forum though I am substituting a different 40gr bullet than what is listed. One of the members on that forum has a downloadable document with a fair bit of data from load testing he has done, be aware that this was not pressure tested though.
Longshot appears to be a favorite for the 5.7x28 cartridge from what I have read, also True Blue. Hodgdon has published load data for AA5, AA7, and True Blue if you have, or can get, any of those powders.
I intend to get out tomorrow and shoot my handloads, if it isn't raining I may chrono them while I do my sighting in to see what kind of velocities I'm seeing with the two different bullets and varying charge weights.
I feel you there, I wanted to try Longshot but could only find it online and UPS shipping costs for powder/primers/loaded ammo are a complete joke so that option is out, hence my experimenting with HS-6 which apparently is pretty decent for the 5.7, hoping it's true.Let us know how it goes…, been looking for those powders you mention, but they seem to be out of stock everywhere
I got mine out to the range yesterday as well. Have a Primary Arms SLX 3x Micro Prism on mine, it works, though the eye relief could be better. Could not utilize the most rearward picatinny slot to help with the eye relief issue as the mount was interfering with the bolt in that most rearward spot, but it clears when moved just one slot forwardI took it to the range yesterday and was impressed by its performance. The build quality is excellent for the price, and it operates smoothly. The left-hand bolt is really intuitive and I wouldn’t have it any other way. Pistol grip is really good as well, better than that on my APC308.
While using an Acro red dot sight, I had 1-inch groups at 50 yards. I’m sure pairing it with a scope could improve this, though its not what I'm looking for in this gun.
Overall, this is a fantastic backpack gun, and I hope it sees great success so that Dark Mtn arms can support more calibres. I’d definitely be interested in collecting various barrels and bolts in the future: 22LR, 17 Hornet, 221 Fireball would be my picks.
Would also like to see some accessories:
- something to clamp on the stock with ring to secure a single point sling
- some sort of picatinny side-saddle that could hold extra rounds on the gun
- dedicated case or some sort of parts blanket
The minimal approach should be maintained with any extras optional of course.
I did have 2 round out of 50 do that. It got hung up and I had to pull back and push in. Was loosely tossing them in the port so not sure what caused it.

Also shooting at 50 yards, my handloads with Speer 40 gr Varmint S.P.'s were around an 1-1.5" for 5 shots, I think there's definitely room to improve there by a fair bit. My intended subsonic loads with Hornady 55gr FMJBT were a little faster than anticipated and slightly supersonic(~1200 fps), but shot great, just over a half inch 5 shot group with 4 of the five all touching, wish I had that accuracy with the faster loads which I had at around ~2460 avg. fps with no pressure signs, however they are rumored to show up quickly in this high pressure, small volume case so I'll be moving up carefully and very incrementally from there.
Agree that it's a well put together gun for the price, only issue I found(and it may be due to buller shape or cartridge length of my handloads) was that I was getting cartridges hung up when closing the bolt unless I pushed them at least partially in to the chamber. Never did try loosely tossing a round in to the loading port with the longer and pointier FMJ (almost) subsonic rounds to test if it was more due to the stubby Speer bullets or not.....next time I guess. Have some Sierra 40gr Blitzking's to load as well, they have a very different bullet profile than the Speer's so I'll see how they feed by comparison on my next outing.
I really enjoyed shooting mine, no regrets at all so far in a very limited sample size, quite happy with the purchase. I think this will be a very fun gun to plink and hunt small game with.
I tried a Vortex 3x prism that interfered with the bolt, switched to a Sparc AR for now. I’ve been looking at those PA slx micro prisms. How does the cheek weld line up with the riser? I’ve added some of reusable camo wrap on the wire stock because it’s been cold as hell. I fired 1 box of the Federal AE 40gr fmj and was getting 1” at 50 yds. As mentioned above, I also had 2 small hang ups that needed a quick back and forth with the bolt to get them seated in the chamber. Looking forward to .22 LR conversion.I got mine out to the range yesterday as well. Have a Primary Arms SLX 3x Micro Prism on mine, it works, though the eye relief could be better.

Ya, that's what I've been wondering, guess no word yet? If not the centre fire cartridges, the rim fires shud already be goodReceived mine earlier this week, waiting for an optic and ammo to arrive. Ordered some dies as well.
Seems like a quality little unit, excited to get it out.
Marstar, in the original thread the short barrels were discussed regarding the possibility of it being NR, will you guys be submitting one to see what it gets classed as?
Barrel length isn't really a concern as it's a single shot bolt action. It's the OAL that's in question, the interpretation is that it doesn't fold or telescope under 660mm, like the Mares leg, but given the initial classification issues, I'm wondering what will happenYa, that's what I've been wondering, guess no word yet?

to go{short barrelled} based on current legislation. ....No?
It can be a concern. Mares Legs come in two barrel lengths, with the shorter (9" version) being classed as a handgun.Barrel length isn't really a concern as it's a single shot bolt action.

Cheek weld is ok, but would be better if I added a riser of some sort to that metal wire stock. Tempted to try and play with a small piece of 1/2" pipe insulation or something like that. I couldn't use any of the cantilever mounts that came with the optic because they brought it up too high, though it would have been nice to get that eye relief, but not at the cost of having a chin weld instead. I'm pretty set on trying to make this optic work, I like having the small amount of magnification, and it's smaller and lighter than any scope I'd be able to drop on there. A Leupold FX-II Ultralight 2.5x20 is in thesame weight range and might be the one conventional scope I'd be interested in for this gun but I haven't seen one for sale anywhere in a long time now, I feel like they might be discontinued.I tried a Vortex 3x prism that interfered with the bolt, switched to a Sparc AR for now.

Still listed as a pre-order on their site, so probably a bit of a wait for those still:Any update on the 9mm version?
