Scope question

Post by infidel325 » Fri May 20, 2016 1:15 pm

I have a RRA Lar8AR standard operator AR 10 .308
With a Vortex diamond back 1.75-5 scope and a RRA ar high mount 1 peice scope mount. Im going to the manatee range next month and would like to shoot out to
1k yards. I have herd about shimming your scope and or mount to get extra MOA but i dont know anything about it.
Is it possible with my setup or should i just get new rings?
If so can you reccomend me some for the AR 10?
I would rather use what i have than have to change it.

I only use Burris Signature rings, and buy extra posi-align inserts in packs so I have the correct adjustments needed. May cost more, but always seemed like a little bit of money to save some tedious work and worry.

Respectfully, You're going to have trouble seeing the target at 1K with a 5X scope. Having said that, if you have a good 100 yd. zero - dial up 36 minutes on the scope. This can be done at home. If the elevation turret runs out before you hit 36 you need to change mounts/rings.
On a side note, a 20" barrel reaching 1K accurately is very hard. Think match barrel, hand loaded match ammo, and a very experienced shooter on the trigger.
Post how it turns out.

Yes, at that range you'll probably need higher magnification and a spotter with a really good spotting scope, and good handloads or quality match ammo. I must say I had the 1,000 yard shooting bug, but I ain't that good upon actually getting down there. The 540 yard (or is it 560?) intermediate target area was the most satisfying for me, but I'm not a dedicated rifleman, more of a bench rest hole punching for fun kind of guy.

I don't think 36 MOA is enough. I think he will have to come up 45 moa or more. I do not know of a spotting scope that can see holes at that distance. They may use protected cameras now and you 'see' the shots on a monitor. Shooting 600 yds can be a humbling experience. I knew a guy who set up at 1000 yards and after 10 - 15 trips out to the target was never able to tell where he was hitting.

It's a lot easier shooting on a range with active pits - someone to mark targets. I figured 36 would at least get him in the black, my 1K zero is 31 on my 308, but it's a purpose built match rifle.

To me, in addition to only 5x power, that scope has a 100yd fixed parallax and unless you can guarantee that you can put your eye in the exact same position for every shot, it is going to cause you problems hitting the target at that range.

At 1000yds, every error with a 308 is magnified. A missed wind call, a bad trigger squeeze, a slight flinch, much less an off centered parallax, all will guarantee that bullet is not going to go where you wanted. And that is with a good setup, gun, scope and ammunition.

If you are serious about shooting 1k, I would get equipment that at least makes it easier to make good hit.

They make 20 degree rails which basically changes the angle your scope points to allow centering the reticle at a longer distance.

I have one on my 15LB AR 26" (Yes Steve, it is Glockpacker's custom build, still have it) and it still allows for use at 100 and 200 yards fine.
I doubt you will not run out of clicks before 1000 and even if you don't you will be basically looking at the edge of your glass and have no parallax at all

As Ark mentioned without the ability to adjust parallax you are all but wasting your time and certainly your ammo

This is a solid answer!
5x is simply not going to cut it at 1k. I've done it with a 3-9 and while doable,wished I had more magnification. 10x is the least I'd consider,but I don't run over 15x generally at 1k. Inside of 600,5x would be ok. This is not to say at all its not possible,but it would be a waste of time and resources IMO.
Well then get your s';t together.
Get it all together. And put it in a backpack. All your s';t. So it’s together. And if you gotta take it somewhere, take it somewhere, you know, take it to the s';t store and sell it, or put it in a s';t museum, I don’t care what you do, you just gotta get it together.

Thanks for the replys. I think im going to go with a different setup. Bushnell elite fixed 10 with a 20 moa mount. Keep it simple and cheap. Maybe find someone with it to trade out my scope and mount!

For a fixed 10x,SWFA Super Sniper line can't be beat. The very best for the money in its class and a very good scope.

I have been using those for over 15 years.
The newer 10X side focus with Mil lines (not mildot) is the best choice IMO

That pic is Eric Keyes . Otherwise known here as Glockpacker.

I thought Wulfman was talking about this particular rifle, but maybe not.

Yes, old picture, maybe 12 years ago, as Eric was just starting his High Power career. He got to be very good at F class, and travelled the country to multiple big matches. Spiders - didn't you shoot with him for quite a while? I know Steve did.

RIP Eric!

Roger. With that hat on I couldn't tell which one, both put some weight on over the years. [smilie=011.gif] Keyes was indeed a great guy both on the range and off. Before his passing he lived about 10 mins.away from me.

RIP Eric :ber
