Well Ive been surfing the net for a couple weeks now. Trying the to find the best out of the box (or near) AR to do some 200M precision shooting.

From what I read so far, I want to get a fast twist (1:7, 1:8) to shoot heavier bullets which will help me acheive more precise shooting.Long Barrel (20inch +) to keep the velocity up and a Bull barrel seems to be a must, for range shooting which allow more shooting and less waiting time

I found this and got me quite impress, making me lean toward bushmaster predator now. Which was not on my list before which was DPMS STAG RRA

Only one Downside no bull barrel. This is the first time I see actual shooting result. I kind like what I see :D

A couple of months ago I bought a Bushmaster Predator to go varmint hunting the week of Memorial Day. I have had limited military training but have not shot in awhile because of college. After a friends recommendation I bought a Bushmaster Predator, Super Sniper scope, Harris Bipod, and a MagPull Stock. put it all together and was shooting BlackHills 77grain. This past weekend I traveled to Alabama to meet with Jim Davis to tune me and my new toy up. Jim works a gun store in Alabama in his spare time and is himself an accomplished marksman. I was proud of the performance and wanted you to know.

300yd Shot

Check out Rock River Arms for their accuracy claims for their A4 Varmit uppers.
The one I have will easily shoot better than advertised with quite a few loads.
Les Baer claims sub 1/2 MOA @ 100yds for his ARs.
 
I think that might be a lucky group. 1/2 MOA is 1.5" @300 yards...and this guy came in at half that. I suspect he is letting the rifle cool between the shots and probably had no wind to deal with.

Not to slag his rifle or his shooting...but 5 round groups tell a better story than 3 round groups do IMO. If he can do that several times in a row under these conditions I will retract my comments and apologize for being suspicious. One lucky group does not tell the story! Inherent accuracy is repeatable.

Regardless, the gun will outshoot you under field conditions anyway which is where it counts IMO.
 
3-shot groups mean squat.
He should try 10-shot at least (if he wants to prove anything),
and even better is a total of at least 10-15 consecutive groups
of 10-shot each on the same paper.

And judging after the size of the bullet holes,
that group looks bigger than .682" (but I was wrong before).
 
A properly set up AR is capable of excellent accuracy (note he didn't say what was done during the "tune up"). Dlask and ATR both make precision AR's here in Canada, and you may want to take a look at those too.
 
I think you have the right idea. I agree with the comments about a singular 3 shot group not being all that telling. Not that I wouldn't be that happy with what he shot, but I typically shoot 5 or 10 shot groups with my AR to give me an evaluation of what the worst case scenario is because it means little to me if I shoot 3 through one hole once. Can I do it again and again?
 
I could post a photo of a three shot 2 1/2" group I shot with my AR at 500 metres. That's well under 1/2 moa. 1:8 barrel, 68gr. Hornadys, Falcon Menace scope set a 5x. Wouldn't mean a darn thing. The rifle can certainly group under 2 minutes, but a sub half minute 3 shot group at 500m is a fluke.
A well set up AR can be very accurate.
A 1:7 or 1:8 twist barrel and heavy bullets do not guarantee precision. They do perform better at long range than lighter bullets, because they work better in the wind.
The group in the photo? Three .22 holes edge to edge, touching = .66. There is space between the holes. That group isn't .682.
 
Three 22 holes touching edge to edge would be .66, but that's measuring outer edge to outer edge, not centre to centre. Could that be the difference?
 
I don't think it would.


tiriaq was referring to the theoretical situation of 3 touching holes,
as for anybody to understand what .66" looks like.
He also sez the holes in the actual picture have spaces between them.
Please note that in the pic.

IMO, in that pic, in the spaces, you can fit 2 more bullet holes.
That makes a total of 5 bullet diameters
and because they are somewhat in-line,
we can imagine the group as 1.1" or so (outside-edge to outside-edge).
Substract a bullet hole (or two half-diameters) and you are left
with .88" or so center to center.

Or if you don't like that, you can scale that picture.
An American quarter is the same diameter with the Canadian one,
.956" or so, depending how much it is worn out.

According to his math he is going edge to edge then subtracting diameter of bullet to get centre to centre.
Also the coin is a nickel--- diameter .835in.
 
Lets get back to precision factors

I just realize I forgot something 223rem or 556 nato.
Stag rifle are chamber 556
I read that firing .223 rem in a 556 will cause accuracy lost to some point.
Since, I am after accuracy cause bench shooting is the only thing I can do in Quebec. Do I need to get 556 or 223. I will moslty shoot reloads If I can find my empty brass.
Where can I buy 556 nato ? is price simillar to 223rem? Im pretty sure Le baron dont have it.

RRA 223WYLDE might be a better option, but again a "In between" when looking after accuracy might not be acceptable.

some feedback in this particular issue would be nice
 
I'm FAIRLY sure 3 shot groups were invented by dudes trying for a good 5 shot group and getting scared to shoot further at 3.

I use 5 shots as a minimum. 10 is nice, if I can afford it.
