My First AR-15..

My guess is that you have a 1:9 twist on your AR, tthat is why the 60grain v-max is working for you. If your really interested in getting the best for your gun from Black Hills, call and ask to speak to a .223 expert. They will take the time and walk you through the different ammo they have and for what you want to do. Be sure and tell them barrel length and twist. Mines in the shop right now getting a new barrel and upper.
I am going with a 1:7.7 twist barrel, 26 inch long bull barrel with a new LaRue tactical handguard. I shoot coyote's at night and wanted a better barrel than what came on my Bushmaster Varminter for heavy grain bullets.
I am shooting a Nightforce 3.5x15x50 illuminated scope with Larure SPR base.
I will post a picture when I get it back from the smith

I believe the RRA Varmiters of all barrel lengths uses a 1-8 twist, I know my 24" Varmiter is a 1-8. It also loves the 60gr V-Max. I use 26.5 Varget & it will place 5 under 1/2". Misfire, you may want to try the 77Mk as well, my gun likes those better than the Hornady, with 24 gr Varget. These group slightly better than the V-Max, yea it is a shooter. Approach those charge weights with caution.

BTW, the guarantee 3/4" groups. Check them out at Welcome to Rock River Arms' Online Show Room

I have a 20 inch RR Varminter. I shoot the Red Box Black Hills 50 grain V-Max bullets. It is a real shooter. Below is a group I shot at 300 yards with a slight left to right wind, and using my first crosshair down with my Leupold VH reticle. The crosshair is sighted in at 200 yards.

The trigger on my rifle is fantastic, I see no need to change it. Tom.

Thanks for the replies everyone. It's been a while since I've revisited this thread and it's grown a bit.

I haven't had a chance to shoot the rifle as much as I'd like to but I did manage to take it out to 200 yards a few weeks ago. The little 18" barrel is a real shooter. I've been quite impressed with it. My reservations about the short barrel have long since been laid to rest.

The barrel is a 1:8 twist and the trigger is the Rock River 2 Stage "Match". It feels good and I like it but I have to admit that it has taken some getting used to.

Here is an honest 200 yard bench group shooting the 60gr V-Max Molly.


Here is a 110 yard off hand one shot group. This is the type of accuracy I was hoping for.




I know it's a very trivial detail but I love the fact that the entire rifle fits into a compact take down shotgun case.

MINE IS A 24" VARMIT AND IT LOVES A HANDLOADED 69grSMK OVER VARGET THIS GUN WILL SHOOT IN THE .2'S ALL DAY LONG AS LONG AS I DO MY PART. YOU WILL NOT FIND A FINER VARMIT AR THEN THE RRA, THIS GUNS REPUTATION PRECEDS ITSELF.

Nice rifle. I have a Bushmaster 16" M4 profile barrel 1/9 twist and it seems to like BH red box 40gr VMAX. I was really surprised with the accuracy out of this barrel! Even with the short barrel, I chrono'd the load at around 3400fps. Shot my first coyote 11/25/07 with it as well. First shot hit it in the jaw and bust it. I didn't discover this until I'd tracked it for 1 1/2 to 2 miles following the blood trail through the snow and mud and finally dispatching it with a head-shot. I need to learn to judge distance better, as I had held high on a full frontal shot at 150 yd. Sorry no pics.
