Results were fairly meh, I'll analyze more closely tonight, but no home-runs. Strangly, I never had to open up the gas system any, even at 2200 fps loads, which seemed odd.
As to other inputs, heh, the MDRx is a whole other animal, and its accuracy issues in the medium size round catagory is repeatedly being seen form among those who bother to actually do more than youtube "it works!" Or cherry pick one good group. It's a whole different animal with all kinds of different nuance that neither my AUG (223 bullpup), nor my AR10 in 6.5 CM have.
Very cool gun, but you can literally move the barrel with your hands. And yes, it's been back to the factory, they replaced the barrel and then said this is as good as it gets. The issues are multiple. With gas system in the wrong spot, trunion too weak and anchored in a strange way, and barrel profile with thin section in an odd place.
That said, I like 6.5. I like bullpups. This is the only game in town. What I really want is a light KelTek in 6.5 Grendel - thats not an option. The MdrX is actually quite reliable, and just a cool fun-gun to shoot. And it looks cool, so there's that
It's a good gong-range gun, but not so great a bullseye gun. Good enough for hunting, but not hunting at the full range of the 6.5CM round likely.
It has the craziest load specific POI shifting as well (also horizontal). Where you have to change zero by 6+ MOA depending on what ammo being shot. But it does that repeatable at least. It's something shooting one load at 200 yards, then switch ammo, look up the reference zero dope, click over a full 2 MIL per prior records (thats a lot), and first 200 shot be the same impact on target, with the different ammo. That's the MDRx. Recoil isn't bad, a good bit better than same weight ar10 6.5 cm, that part is good
So anyway, yes, my question was: if I greatly decrease the strain on the system (gas, trunion, et al), will I decrease the extent of shot to shot variation, and decrease the incident rate of SUPRISE 4 MOA horizontal flyer? (Heh and no, I'm not yanking the gun off by 4 MOA on the rest somehow). The answer... maybe, but I didn't exactly throw a lot of 1 MOA tight groups to prove it. Will study the targets when get more time tonight.
