I am looking to buy a new scope for my ruger m77 mark11 .300 win mag. I have a budget close to 1000 dollars. I would like to get a ballistic turret so i can change on the fly. A couple scope i have been looking at are the vortex pst, ziess conquest, swarovski z3, leupold, and the huskemaw. I guess my real question is the vortex up there with the swarovski or ziess or should I just spend a couple hundred more.
