Nice choice on the Zeiss. You won't be sorry making that decision. The VX-III is certainly acceptable but IMHO the Zeiss is better for the $$.I am using a 300 WM comfortech with a 3.5 x 10 swarovski similar to your Zeiss. . I am getting about 1-1/2" groups with winchester ballistic silvertips 180grain. If I could do something about this %*&@!!! trigger, I think the gun would shoot under an inch. The SC season is next week , so that issue will have to wait til after the season is out. The 180 gr 300 Wm round is devastating. I have shot 2 300 lb+ whitetails in Canada with this round and it dropped them both in their tracks. sounds like you made all the right choices. good luck.
