Have a look at this review of a Rock River Arms Varmint A4. Plenty of information about the accuracy of the rifle.

Anyone can read stats, but this is for the real rifles out there. The ones you built or bought, that what I want to hear about. Your shots and scores.

 

[Master-G]

Rifle: Colt Sporter Match HBAR with Armalite flat-top upper, factory 1:7 barrel, factory A2 flash hider
Optic: Elcan
Ammo: Lapua 69 grain Afficionado
Distance: 100m
Group size: From a rest, 1.1"

I am just starting to reload for my Stag.

Rifle:
Stag 1R
16" 1/7 twist barrel
TA01NSN ACOG scope

Load:
69 gr Sierra Match Kings
24.5 grains of Varget
Federal 205 Primers
OAL 2.250
Remington brass
A light Lee Factory Crimp (1/4 turn)


At 50 yards it shot about 1/3 inch 5 shot group. This is off a bench rest, with a hot barrel and without me really concentrating too hard.

I plan on doing some load development and taking the rifle out to a 100 yard range soon.

 

[sparhawk]

colt tactical carbine, 16" 1/9 hbar, ACOG TA31F, winchester Q load 55gr, 1 MOA five shot group standing to prone snap

done by GT himself

 

[agilent_one]

3.5" groups w/ WWB .223. Limiting factor is the EOTech. I would expect under 1" with a scope.

Rifle: Eagle lower, Armalite LPK & RRA upper.
Barrel: Wilson CrMo 1/9. 14.5"
Muzzle Brake: Smith G6 Vortex
Sights: EOTech

 

[freddy]

hbar a2 configuration 1/7 20" $80 bushnell 3x9
62 grn ruag surplus 1.1 at 100 yards
69 grn federal match 1.1 at 200 yards

 

[ssgp2]

CLE upper 24" kreiger 1/8" on top of a Eagle Arms with NM trigger.

It will shoot any of my reloads in the same hole if I do my part(45gr up to 80gr).

Actually boring to shoot at 100meters.

 

[Helno]

I have an old CQ-311 with a 20 inch chrome lined barrel with 1 in 12 twist rate. It is really dirty as I have been seeing how long until it will start to jam adn I fired a 10 shot group into 4 inches at 100 yards with my cheap chinese carry handle scope.

 

[shortandlong]

that aint bad for one of those ....i've had better than 1 inch 100 with my issue C7 with an ELCAN
(this was at prone)

I use a 77gr Nosler at 2775fps (Varget - a compressed load that is theoretically unsafe by SAAMI spec).

I only shoot 10rd strings for groups these days.
There is a great thread on AR15.com as to why.

the majority of my groups are in the 1MOA range (S&B Short Dot set at 4x) with a douglas 16"

I have Krieger, Novekse, and Llija barrels as well -- they do similarily
(all my barrels are freefloated)

My Colt 14.5 RO921HB bbl - hovers at 1.5MOA with that loading.


The tightest groups I have shot are with issue Mk262 Mod1 (BlackHills seems to sell their lesser loads to civilians, as the bought clone stuff I have here and in the US is not as tight.

 

[Musky Hunter]

Rifle: Bushmaster 11.5"
Muzzle Brake: Standard
Sights: Holosight
Ammo: Winchester "White Box" 55gr FMJ
Groups: 1 1/2" or so

 

[acrashb]

JP Rifles CTR-UA, .308" 5-shot at 100 off the bipod. Lapua69gr Scenars, magazine length. Going to try some Sierra 80gr's single-fed and see what happens. RL15 all around.

Hello Kevin,

Have you had a chance to try the Federal Gold Medal Match 77gr HPBTM? I was wondering how close to the MK262 Issue stuff it is, ie accuracy trajectory etc... Thanks

 

[m0nkyman]

A lot better than I can shoot. I've promised myself good optics when I can place five shots inside an inch with iron sights... The gun is capable of it. I'm not.

Oh, I'm using a Bushmaster XM15 E2S Dissipator A3....

 

[KevinB]

Both the Fed and other SAAMI spec 77gr is about 100-150fps slower than the Mk262.
I typically shoot red box BH 77's in Fla when shooting for groups -- I am unimpressed with the Fed Brass - so I dont shoot much. Accuracywise (IMHO) it is a bit off the Mk262 but similar (and more $) than the BlackHills civilian sale loadings

 

[ssgp2]

I have tried the BH 77gr in my 24" and I got 2600fps.
Not very impressive...
