So from all the articles I've been reading, I hear the ballistics that the Leica 1600B gives is completely off and you can't even input your ammo weight and BC... Why does everyone spend the money on this if the ballistics function is useless? Why not save the money and get the Leica without the ballistics? Should I get a swarovski instead? I only have 800 bucks to spend and I only need to range 900-1000 yards MAX... Mostly 400-600. Any recomendations?
