Do these BDC scope work with amount of accuracy? I dont understand how they can comensate for different bullet weights.

Ive got Leupold with cds that works very well.
 
The dots/lines in the reticle are simply spaced out at a certain distance in MOA, at the highest magnification. If you know that your load requires 3.5MOA of elevation at X yards, then you hold the dot that is 3.5MOA below the crosshairs on the target. Very simple to calculate the drop using a good ballistic program, like JBM, and then verify at the range.
 
With the Zeiss Rapid Z system, you have to choose the most suitable reticle for your load. From there you can fine tune using the magnification. Unfortunately, some cartridges just don't match up any of the Zeiss reticles, and not all reticles are available with all Zeiss scopes.
 
I don't like any of that stuff. I find it clutters the scope to much. I know my gun, as long as I know the range to a certain degree, the regular cross hairs should work every time, for the shooting i do anyways.
 
I have a few, I like them for hunting purposes. I have a Burris fullfield II that works very well with my 7mm-08. I think if you spend the range time with them, and know your ranges in the field they can work well.

x2 take time to verify any discrepency at the ranges you intend to use them at. I don't think I have any business shooting at big game at ranges I've never verified my ability at.
 
I have found that the 4.5-14x40 B&C , works the best , I've got my 7 rem mag , 338 win mag to hit right on target out to 500 yards , With no tuning needed to the scope ,

Other magnifications Of the B&C I have had a battle with , and the Zeiss 800 and 1000 only seem to be accurate enough to 500 yards anyway .

Just my two cents
 
As long as the reticle doesn't break, the spacings on the lines should last a lifetime and not move.

Does this match anything you will want to launch? Absolutely!!!!.

You can pretty much be assured that the bullet will land some distance away from you when one of those markings is placed on a target. And if you adjust the location of the target, the two will coincide.

Assuming, the reticle doesn't break and the ammo stable under temps and you shoot consistently, this will occur repeatedly.

BDC work. Question is does it do what you want?

I found the same thing at first with the Zeiss Rapid-Z. The reticle was too busy for my eye but I got used to it. Now I love both the Rapid-Z 600 on my Conquest and the BRX on my Swaro Z5. No more clicks counting or guessing and the ballistic calculator on Swarovski's website is amazing to use with any load.
 
Scopes with the BDC systems

I guess I'm going to date myself here, but that's OK. There's an old saying YOU GET OUT WHAT YOU PUT IN. With these scopes you have to go to the range and try it out. Record your results and you're good to go. THERE IS NOTHING ON HERE, that will be more accurate than hands on learning.

if you think that's busy, i have a old scopechief that has BOTH a RANGEFINDER and a BDC built in- the range finder uses the old stadia wires concept, and then you "dial in" the bdc when you've used the range finder- it's got parallax adjust too, so i just leave the works set for 300 /180s and shoot- that's 1976 vintage technology folks- OPTICAL RANGEFINDERS and wheels- just like the things they used to call conicedence rangefinders
