Hey John, take a look at the Zeiss Conquests with the RapidZ 800
Welcome to Carl Zeiss Optical, Inc.
With this system it is not true that the reticle is only good for a certain bullet at a certain velocity. Use the RapidZ calculator on their website to calculate the power to set the scope on to match whatever load you are shooting.
For example the calculator says that for my 300 win mag load shooting a 200 gr Accubond at 2900 fps the power would need to be set on 11.37 power for the reticle to be correct as follows:
crosshairs - 200 yd zero
1st bar - 294 yards
2nd bar - 395 yards
3rd bar - 496 yards
4th bar - 600 yards
5th bar - 705 yards
6th bar - 812 yards
Or for a 180 gr Accubond at 3100 fps set the power on 12.46 for
crosshairs - 200 yd zero
1st bar - 296 yards
2nd bar - 398 yards
3rd bar - 499 yards
4th bar - 600 yards
5th bar - 702 yards
6th bar - 804 yards
That's pretty close and you will have a Zeiss. My 4.5x14x44 RapidZ 800 costs me $659.00.
