AR10 308 - would you be satisfied?

[moog5050]

So after finishing the second redneck blind today, I sighted in my new AR10.   Besides wasting a bunch of rounds due to a loose mount,  it seemed to zero in reasonably well.  Started high and then overcorrected low and gradually moved it up but my last 5 shots are those in the black circle including one of the 2 with the dash next to it.  Not 100% sure which one.  In any event, would you be satisfied with that last group?  It’s not clover leaf nor close to my best group  but I guess decent for a 16” barrel semi auto.   Definitely minute of Deer.  Honest opinions?  

Photos are sideways.  Black circle was top of bullseye.  And shots at 110yds. I could add a click or two left but breeze was blowing that direction so I left it as is.

same as the AR15, it seemed to shoot better the more rounds I put through it.   Maybe the oils from manufacturing need to burn out.  Not sure.

You didn't mention the ammo used or barrel spec, but I'd say a 1.5" group at 110 yds fits that profile.  Nice rig, should drop some deer!

Used the same ammo that my Sako likes. 308 Winchester powermax bonded 180g.  The barrel is a fluted medium heavy 16”.  I might be able to tighten it up with different ammo but I have lots of the powermax in stock.  Lol

Anything in the 1-1.5" range and I'd be very happy with that particular setup.  As you said, it's for hunting not precision shooting.

Thanks Jdubs.  I generally agree but tend to expect more.  Lol

Nice rig for sure.

Bout time , need to see some big holes.  Ones you can't help but cloverleaf cause of the size!  Lol.  

Been looking forward to seeing how that shoots for sure.

Z3?

How does it track?

Yes - I didn’t box test it but it seemed to track true at least within the accuracy margin of error. 

[Pygmy]

I would take it out again and shoot a couple of 3 shot groups...If they are 1.5" or under, I would be very satisfied..Good hunting accuracy...  If not, I'd play around with some other bullet weights, such as 150 grain or 165 grain...

A dead deer is a dead deer brother.  It won't be any more dead if you hit vitals .2 MOA better.  

Unless of course you're lining up a Texas Heart Shot like wolc then maybe you'll need to thread that brown-eyed needle.

True.  I will get it out once more now that it’s sighted and see how it shoots next try.  I think it will hold that 1.5 moa range which I guess is fine especially at ranges I shoot.

Whats the twist rate on the barrel? That should help pick the bullet gr.

It’s a faster twist than some.  1x10.  Should be good with heavier 308 like the 180.   I am guessing anything lighter than 165 will be too light.

Like u said it should like 180's then. Shoot it more it may tighten up. Im kinda picky, im a 1moa kinda guy. Thats as big as i want my groups to be.

I agree Gen.  and it does seem to be shooting tighter the more I shoot.  My 6.8 was the same.  Might be an AR thing breaking in.  

That said, I also agree with Jdubs, it will kill Deer just fine based on my last 5 shots.

Yep im hoping to hit a even .5 moa outta my grendel as i shoot it more.

[ny hunter]

Nice rifle  for sure....I would another ammo just to see if the gun does better....not that there is anything wrong now.

[grampy]

Just shoot it more. Most all my guns can out shoot me. But I get better the more I shoot them. That is a nice looking rifle! Can't wait to see it in a picture of you, and one of those big WNY bucks, this fall!

[fasteddie]

You don"t need 10 bullets to kill a deah . ( Prince Andy ) .                                                          9

[Pygmy]

If I needed a 1" group, I'd have to have throw away my best hunting rifle, the one that has killed many game animals all over North America in the last 40 years....

It is a push feed Winchester M70 in .280 Rem, and on it's BEST day it might group 1.5" at 100 yards, but 1 3/4  to 2" is more the norm...

"Cloverleaf" type accuracy is nice for bragging rights, but not necessary for a hunting rifle...

Something I noticed that would help groups is to get a free float handguard. With that it will free float the barrel. I wouldn't be upset with that circled group at 100 yards. That last group looks real close to sub MOA, out of a 16" barrel and semi auto that is a nice group. Some bolt rifles don't shoot that nice.
