Rifle Scopes AR-30 w/ Zeiss Conquest Z-1000

[wIg SpLiTtEr]

My buddy recently purchased an AR-30(300 WM), Zeiss Conquest(6.5-20x50 w/ Z-1000 reticle which is technically rated for .308), and a 20 moa nightforce unimount. Were trying to get out to 1000yds with this setup but cant seem to get all the hash marks to work out to that distance.. We called Zeiss prior to our purchase and the rep said the ballistics of the 300 WM would be so close to a .308 that it wouldnt really hurt anything. That being said, does anyone see any problems that would arise with this combination? Is this type of scope sufficient for what were trying to do?

The zeiss 6.5-20 has limited internal elevation for turret twisting to 1000 but there might be enough for a 300 mag with the right bullet.

The z1000 reticle was designed to be adjusted to your rifle/cartridge by adjusting the magnification to a certain power, then leave it there and only use it on that power. You never touch the turrets or the magnification EVER AGAIN....NEVER. Or else your shots will be off at ALL ranges except the range at the intersection of the 2 main cross hairs. There is a calculator on the zeiss web site to determine the power setting. if you follow their instructions you can be on at 1000 yards. However you can never change the power.

And the drop of a 308 compared to a 300 is not that close. How close is going to depend on your expectations. Are you shooting at 1 MOA size targets? Or 5MOA size targets?

You sure can tell who has used one and who hasn't. use a 6/24 diavari z1000 on a trg, one of my favorite setups. starting with a 308 first then how to adjust it for a 300 wsm or mag., a typical 308 will have about 3.3 mil drop to 500 yds. (using my load as an example). so after sighting in at 100 yds, I have 2 options, and can use the center reticle and just dial in drops (mines in .5mil so double everything) and can use this feature at any power. To "activate the hold over hashs" simply dial in (my load) 6.4 mils. and the hold overs marked will be at the yardages indicated. The biggest draw back to using the z1000 is that the target is at the edge of the optical field and unless you have really, really good glass lots of distortion, inability to watch impacts. the diavari has really good glass, but the fov impact zone is still really small.
adjusting for higher velocity 308 bullets, simply requires using a ballistic program such as JBM for the load your using, then simply note at what ranges the hash marks coincide. They will not be on whole numbers such as 200,300 etc. but something like 225,349 etc. This isn't the problem as it sounds because a target is rarely at even yard or meter intervals anyway.

should add that the optimization feature at the zeiss site raises the poi by reducing the power in sfp scopes, such that at some power levelthe hashs will be on or closer to the 200 yd, 300 yd hash marks. If you use this feature you should make a tick mark on your power ring so you can get close to the same setting each time. Unfortunately there are no click stops.

First of all he is using a Conquest, not a Diavari. Yugo vs Mercedes. But the reticle is the same.

Second, what you said is what I said. The only stable aiming point is the cross hair intersection. Magnification changes do not effect this point only.

If you set it up like Zeiss recommends, then your short range zeroes will be off if you change the magnification. And if you use it as a turret twister, only using the cross hair intersection, then you are bound by the limited elevation travel.

Re: AR-30 w/ Zeiss Conquest Z-1000

just like I said etc. the diavari will not dial to a 1000 without a 20 moa rail, and again you can calibrate the reticule hashs for any power range you want, you are not locked into using the reticule per definition above. as an example on the z1000 dialing down to 12x will move the 300 yd hash to be on at 400 yds.
or using something like the JBM program and knowing the moa drop on the 600 yd hash as an example use that as the hold over and dial in the rest to take the difference out to 1000 yd. If you are using the z1000 your not taking advantage of all the features.

Re: AR-30 w/ Zeiss Conquest Z-1000

shooter2 has it explained well.

Regardless of Conquest or Diavari, the Rapid-Z 1000 can be adjusted to ~1400 yards without a canted rail.

You'd do this with a combination of holdover marks + turrets.

Limited reticle view this way, but quite doable.

Re: AR-30 w/ Zeiss Conquest Z-1000

Thanks everyone for the input! Ive came to the conclusion to sell the Zeiss scope and run with a NF NXS F1. I think FFP scope will do me a little more good than this SFP. Anyways, yalls info is much appreciated!

So is this yours or your buddies... You buying a $2000 scope for a friend's gun?
