Looking to buy a new scope for my 700 AAC-SD .308. Shooting mostly from 100-800 with an occasional 1000 yard shot just for fun. The scope on it before was a Bushnell 3200 10x fixed power with the mil dot reticle mil/mil and I'm looking to upgrade a bit to something with a little more power for longer ranges. Will be target shooting targets mostly but sometimes will take it hunting. I'm looking at the Vortex Viper 6.5-20x44mm that has the variable zoom with side focus parallax in mil dot or the SWFA SS 12x42 tactical. I can get the SWFA in mil/mil which I have used before and like but it is fixed power, the Vortex is moa/mil but has the variable power. I like the SWFA reticle and mil/mil setup but also like the Vortex variable power with more power and side focus. My question is would it be better to go with the mil/mil SWFA and stick with the mil/mil setup and be limited to fixed power or switch to the Vortex with the moa/mil setup but have variable/stronger power and side focus?
