Kahles Scope with bullet compensator question.

Guys,
I stumbled on a great deal on a Kahles zf 84 6x42 sniper scope a couple of years ago. It has a bullet drop compensator for the NATO 7.62x51 (.308, 168 grain) built in. Once it's sighted in at 100 meters, I theoretically should be able to dial the knob on top up to 700 meters. My question is, will this cam correlate to the 7 mm magnum ballistics? I have the scope mounted on an old browning rifle and shooting 150 factory ammunition at 2900 fps.

Does anyone have one of these scopes? Just trying to find some answers. /ubbthreads/images/graemlins/confused1.gif
 
I had a Kahles ZF84-10V2 the one with the "butterfly reticle" 100-900 yards {or meters.} It too was calibrated for 7.62 Nato {308} but I had it on a 30-06 Ackley Improved. As long as I matched the trajectory it would lob em right in there where it was supposed to. I looked in the back of a Sierra reloading manual and found the bullet weight and trajectory that matched as close as possible and then load it to that velocity. In my case a 220 grn bullet loaded at 2550 fps did the trick. Only catch for you is for hunting you will have to slow the 7mm down some. It has one of the best ballistic coefficients out there and shoots among the flatest. You will have to lose some of that to match the scope. Good luck.
 
You need put you up some targets at the ranges you stated and shoot the rifle and see how close the adjustment are with your scope. This is the only way you will know for sure.
 
i had the swarovski with the same thing mounted on a 7mmstw and it was right on the money at 300 400 500 and 600 yards.i was shooting the 160gr seirra game kings.
 
Mike you will just have to shoot the distances to see how close it is. With the higher vel of the 7mm it may be close for big game but non of these are precise as they are velocity driven. I have never seen one work with 168's very well as they are usually set up for a bullet traveling 2550 fps. No factory 168 match round runs no where near that slow now-a-days!
 
At longer ranges the altitude you are shooting at makes a significant difference in trajectory. All rounds shoot a lot flatter at high altitude than near sea level.
