Do you use a 20 moa rail ( or offset insert ) on the Conquest 6.5-20x50 with Rapid-Z 1000?

I have search hard on the net and got mixed answer some said you don't need a 20 moa rail on the Rapid Z but the Zeiss manual said yes.

Special requirements should be met when sighting in the Conquest 6.5 – 20 x 50 MC riflescope.
To be able to use the full range of the elevation adjustment, the riflescope should be mounted on the rifle at an angle of approx. 20 angular minutes with commercially available mounting systems (corresponds to 21 inch/100 yards or 58.4 cm/100 m).

Any thoughts?

The scope has Target turrets with Rapid-Z 1000 (rifle is a .308).

I have not count how many clicks of elevation adjustment yet but according to Zeiss it has 45 inches / 175 clicks and might not have enough adjustments to 1000yds but isn't what the Rapid-z 1000 reticle is for as a hold over reticle?

I did use Zeiss's online ballistic calculator and it appears very close to the load I will be using.

Any actual user's input will be very much appreciated.
 
Either way. Makes no difference.

The whole point of a BDC or christmas tree reticle is to use the hash marks for addn aiming points to compensate for elev/windage.

As long as there are enough lines to get out to the distance you want, the turrents don't get touched (well, kind of, not really).

So you zero at 100yds, figure out which line does what and have at it.

If you still want to dial the turrents, then you will need to figure out what travel you have after zeroing and how you need to compensate. See article on my website in the Tech section.

But if willing to dial, the reticle becomes redundant so....

Right, I believe I'm up about 27 MOA from 100 yards but up from dead bottom about 16 to 100 yards. I'm away at work and can't remember exactly what they are but pretty sure that's darn close. Somehow doesn't seem right though, that I'm up that much from mech zero. Give me a week and I'll check on it.:p

Thanks Jerry and Curt for your chime in and thanks Jerry for the clarification.

I was not quite sure about why Zeiss put target turrets and suggested to use a 20 moa rail with the rapid-z but Jerry hit the nail on the head as this is reduntant because the Christmas tree reticle's purpose is to eliminate knob turning by just aim at the appropriate line and shoot but I guess Zeiss consider this a hybrid so for those who like it dial in their shot still can do it but if one is lazy and prefer hold over /bdc reticle can just aim and shoot.

Thanks for all the help.

They have 1 scope tube and just insert reticles as needed.

That is more then likely the reason. At least you will have options especially when the drop doesn't fit your reticle which is likely to happen often.

Rooster, there is no rhyme or reason where a scope zeros at 100yds. As long as you have enough travel to get where you want to go... leave it alone.

Ideally, I want the elevation to be centered in the scope travel over the ranges most often used. This allows for best scope optics and range of windage adjustment.

Oh, I'm not worried about it or anything, it just seems a bit odd because my .284 used to be a stock Sendero .300 WM which wore the exact same rail & scope. 100 yard zero was exactly 2 MOA from bottom with 210 VLD's. Seems like a big difference to me, being the same action, rail, and scope. Oh well, it works and that's all I really care about!

What will make things a bit more difficult with this reticle is when we want to stretch beyond our turret's range. I guess just backwards from usual procedure would be the answer? Use up the reticle first & then start dialing comeups (as opposed to dial to max, then use reticle holdovers)? The blessing here is, I have a ways to go before this becomes a 'problem'.:redface:

Same parts - very different alignment. All too common.

When you run out of elevation, just shim the scope for a higher zero.

for my 223 to a mile project, I had my full down elevation setting with the bullet hitting 44" high at 100yds. That dropped my bullets around 1450yds. Then I dialed and used up the reticle to make the rest of the trip.

Easy to put a piece of paper much higher then your point of aim.

Not saying it is right, or the only way to do it, but I generally dial my shots on the turret when I am doing range work or plinking and have time. I use the reticle subtension lines when I am in a hurry like a hunting situation. I would use the 20 MOA rail, gives a little more versatility.
