reseting turrets... I dont get it

It is a really useful feature if you want to shoot the rifle at different ranges. Zero at a known distance, set to "0", then establish the settings for different distances. Accurate and repeatable.
If you are only going to zero at one distance, and then hold off for shots at other ranges, it probably doesn't matter.

Better to have your windage and ele, at 0 , than lets say half way between some minute of angle on the dial.. you can sight at 100 , then up from 0 will be 200 , and 300 and so on.
Its the same reason they put arrows, and l/r u and d , keep it as simple as you can
ooo that should come in handy, but im curious, do all zeiss conquest's have the reset feature? I'm reading the manual and it states that I need to turn the 0 on the turret to the index mark on the tube, I don't see a 0 or index mark on mine, it just has a bunch of white and black lines like a barcode but the turret can be pulled up to rotate without the clicks...

If you have your rifle sighted in at 100 yards, and your turrets are reset to zero.......and you know the ballistics of your ammo, you can adjust the turrets and be zeroed for any distance. Example:
My .308 is using 155gr Nosler match ammo at 2830fps zeroed for 100 yards. I know that this round is 3.5 inches low at 200 yards, 13 inches low at 300 yards and much further out......132.7 inches low at 700 yards. If I wanted to make a shot at 700 yards without having to "guess" where to hold over, I simply crunch 132.7 devided by 7 (the MOA) giving me 18.95. Lets just round that to 19. Now I just grab that top turret and crank it counter clockwise one full revolution ( should equal 15 moa) until it lines up with the 4 moa adjustment hashmark. 15 + 4 = 19 moa. Now I am zeroed for the 700 yard shot. Just remember to reset your turrets to your original 100 yard zero after your shot.

I find this feature very useful for long range shooting. I cronograph the load and plug the data into Hornady's ballistic calculator, and when I'm shooting long range, adjust my scope. I have Nightforce, Ziess and Leapold tactical scopes with this feature and they all work well.
could you please tell me what model zeiss you ownÉ and does it have a zero printed on your turret or is it just a barcodeÉ
I thank you guys for the detailed responces, i`ll be sure to use this feature once I join a long distance range.
Hornady calculator error
Hornady's ballistic calculator is excellent. I noticed however that the windage MOA correction only matches the bullet drift, in inches, when calculating a 10 MPH wind.
If one MOA = 1.04 inches at 100yd, or 10.4 inches at 1000 yd, then a 1000yd windage of say 93.3 inches @ 10mph, for example, would require an MOA correction of 8.91
A 1000yd windage of 46.6 inches at 5mph (half the wind, half the drift) should require an MOA correction of 4.48, not 2.23 as Hornady's program suggests. It also gives faulty MOA corrections above 10mph.
Nothing tricky going on. Just basic trig functions. I have been meaning to contact Hornady about this, just havn't got around to it yet.
