Don't mean to be mean. But I have shot the gun. And though I like it a lot, and will even own one very shortly, I can't stand people using hyperbole to describe it. It recoils like 270 winchester bolt gun. I wouldn't say 243. I know a few reviewers have said that. I think it was more. It was less than expected though. I will say that.
The gun holds sub MOA accuracy out to long ranges. I shot it at 1000 meters and it was shooting consistently in the 7s and 8s. Not the 5s. I had groups in the 5s, but only 2. So I simply don't believe people saying the gun held half MOA all day.
I used factory ammo, 300 gr SMKs that BHs made. As well as some HSMs loaded with Berger 300 VLD Hunters. I shot some of my buddies hornady 250 grain factory loads. I don't like the load, but my tightest group was with them actually. As far as factory loads.
I also shot some cheap Prvi Partisan 250 gr rounds. No shock they had a 13.45 average group.
I did shoot handholds, and had to shoot them single shot because they are seated for my custom gun with an OAL of just under 4 inches. Mix of 250 SMKs and 300 Berger OTMs that I had available. Didn't fit in mag. They chambered into lands of course. These were the most accurate of all the groups.
I would say it shot better than I expected. It is a sub-MOA AR without a doubt. Operation was smoother than the other Noreens I have shot. Perhaps the required engineering and tuning for a round of this caliber force Pete to really hone down on this rifle and make it right.
As far as reliability, I had multiple feeding issues, all with factory ammo. I take care of my brass on my reloads, so didn't have issues there. The HSM and Hornady brass did show significant wear marks, almost looking like overpressure marks. Likely due to junk brass they use.
It will be a fun gun to have in collection, and I probably will even hunt with it at least once. Buy it if you have the coin. If you want a extreme range tack driver, build the custom bolt gun. The price tag will be the same either way.
Special note, I do not work for any firearms company or related company. I am merely a recreational shooter with a previous military background. I grew up in MT. I even know a few of the guys with gun companies out there now. Actually quite a few. Some great gun builders, some just ok. Pete is a pretty good gun maker. His company is pretty good. Not exceptional, not unmatched. Pretty darn good. I would be happy owning any of his products.
