I have scored 9 out of 10 hits at 320 yds with my 4 moa T-1. I have no doubt in my mind that it can be done. 320 is about as far as I can get at my house with the topography of my field.
Here is a video of me shooting with a 1.5 power ACOG at 215 yards standing with no sling. The plate is as tall as a standard silhouette but a bit more narrow.

I can make hits consistantly out to 440 yds with my M4s on a torso sized/IDPA steel target. It’s not that difficult with practice using the same ammo and knowing what your drop is.
Now a 6" target at 400 yds would be difficult. If I could get hits on a 6" target on 1/3 of my shots at 400 yds I’d be surprised. With my eyesight, I’d catch hell just seeing it.
Alot of this depends on what position you’re shooting from…sandbagged on a bench, prone, sitting, etc. Ammo choice, trigger… Throw in a good 5-10 mph cross wind and you’ve just added to the difficulty.
IMO if you want to shoot that distance and get consistant hits on a 6" target, get at least a 1x4 magnified optic…your ego will thank you.
I posted this in another thread as well but…
Last month, Defoor Advanced Carbine, 11 shooters, 12 counting Kyle. We shot at A/C steel at 400 yards and the only people that were getting hits were those with magnification, and even then it took some “walking in”. We moved to 300 and just about everyone got at least some hits, including those with Aimpoints and Eotechs, and the magnified guys were ringing it with boring regularity, again after finding the drop.
this was from prone, unsupported (meaning no rest, no bipod, although I think some people may have had grip-pods) and I think it represents about what the typical shooter is going to do. I think for the majority of shooters (shooters, not gun owners) with some level of proficiency 200 yards is about the max, guaranteed, first round hit and after that you start winging them in until you get a ding and then hold there, meaning practical real-world application is probably nil. Not many men or animals are just going to stand there and let you lob shots in their direction at 300 yards until you get lucky and drop one into their abdomen.
I think you are accurate, for me it is only about 100yds with irons for near 100% 1st round hits . I have seen a lot of shooters with big scoped rifles at the club I shoot at be amazed at anyone shooting < 3MOA with irons ,usually equal o there scoped shooting. The hunters are usually worse.
Back in 1989, during USMC boot camp, part of qualifying with the M16A2 service rifle included 10 shots at a man-sized silhouette target at 500 yards (or was it meters?). We were in the prone position and could use our slings off the lower swivel for stability. We also did it with iron sights.
Why do I mention this? Because I don’t find it hard to believe that someone can reach out and touch 600 yards with a RDS.
I was a total noob shooter (still am), and I would have been upset if I didn’t come off the 500 yard line after pre-qual or qualifying with at least seven five-pointers out of 10 with the balance being four-pointers.
Irons are a lot easier to shoot at distance with accuracy than a RDS because with irons you put the target on top of the front sight post, with a RDS you cover the target with the dot.

That missing 2 MOA adds a hundred or two yards to the 4MOA Micro’s accuracy.
I hadn’t thought about it that way. I figured a 2-MOA RDS’s dot wouldn’t be bigger than the iron sights when acquiring sight picture and alignment (do you even have to align an Aimpoint? Lol).
I wish I had a range near me that went to 500 yards or more. I’d love to try my RDS at that distance and see what it looks like over the target. But, alas, I am stuck with 100 yard ranges through the Missouri Dept of Conservation. 
Isn’t the USMC D target used at 500 meters and 6’ tall by 6’ wide? Or the equivalent of 14"x14" at 100 yards?

At distance you have to hold over with the red dot, it won’t be covering the target because it will be above it.
As for the Marine Corps Qual shooting 500 cold is much different than warming up with grass week followed and the at least fourty other shots you already took that day.
The “B mod” target frame is 6’x6’, but the actual silhouette is 40" tall, 20" wide.

No that’s the backboard. The acuall target is something like 18" by 36". I don’t recall the acual dementions.
300 meters on a 12" gong is easier for me than 200m on 10" plates. With a 200m zero, straddle half the dot over the gong at 300, which is an easy sight picture.
I watched my brother in law get repeatable hits at 600 with a 6920 wearing a Comp M4 on a 66% IPSC
We had walked it out from 100 figuring out hold overs as we went.
Depends on how you zeroed your weapon. If your ok with holding into space and trying to guestimate a hold over with no reference points then good luck. But most of us shooting out to 500 yards what a hold point or to be dialed in at that distance.

All the data collected during the days prior to pre-qual and qualifying did make things easier. The only new adjustments made were for windage. Not a whole lot of wind at MCRD San Diego, but at Kaneohe Bay, the wind was gusty and it made for a much challenging qualifying day.
Me too, I have made hits on prairie dogs at 800 but I was using a 24 inch barreled Savage 12FV with a 15X scope. Took me about 10 shots per hit and I could not always see the impacts through the scope. A 55 grain bullet through a carbine barrel will be subsonic at that range.
Yep some of the stuff I see people claim just makes me shake my head.

Since when do you fire for qualification at MCRD San Diego? They don’t have a rifle range there. It’s right next to the airport in downtown San Diego.
Unless things have changed rifle qualification is held at Edson range at Camp Pendelton and there is plenty of wind there since it’s right next to the ocean.
So you don’t have to hold in space with irons? In fact, the FSB may even obscure the target entirely.
