All,
I'm thinking of a Zeiss scope for my new rifle (Sako 85 SS in 7mm RM). I've had a look at the Zeiss Victory Varipoints. I understand that these can be fitted with Zeiss' version of a ballistic turret.
I've had a look at the Kahles and Swaro ballistic turrets and I understand how these work. You zero the rifle at, say, 100 yrds and then rezero it at, say 150. When the rifle is on at 150 you add a disc to the turret. This process is repeated for all three discs. Once that's done you rotate the turret to the marker that indicates the distance you want and off you go .
My understanding (and I may have this wrong) is that the Zeiss system works a bit differently. If I've understood it correctly, the premise of the system is that all combinations of cartridge, bullet weight, charge etc. produce a trajectory which falls into one of about five or six "standard" trajectories. These standard trajectories are worked up into foil tapes, which fit onto the ballistic turret.
Once you know which of the tapes best corresponds to the trajectory of your choice of cartridge, bullet weight etc. you zero the rifle at 100 metres and stick the correct tape on the ballistic turret. My understanding is that you can then dial in the distance to the target quite accurately as the tape has quite small increments.
I've struggled to find a good review of the system on't t'inteweb and I though that one of us may have some knowledge. I'd be grateful for any information on whether I've interepreted the system correctly. Also, if anyone has one, how do you get on with it and does it work ?
I don't have sufficient experience to form a view on whether all cartridge, bullet eight and powder combos can be summarised into five or six standard trajectories. However, I do know that the people at Zeiss know what they're doing and will have thought it through in ways too complicated for me to imagine !!!
I'd be very grateful for any advice.
Cheers,
Bob
