I always use weaver style scope mounts on my rifles and I think it is more convinent to put the scope on and off and keep the zero pretty well. Another reason is I can move scope from one rifle to another rifle as long as I track the adjustment. However, I always wonder why Leupold stays with dovetail scope mount system so is Burris and another major manufacturer that I can not remember the name. What is the advantage of the dovetail system? More side adjustment? How much side adjustment allowed in this system? If too much offset to the side would put excessive stress on the scope? Is the dovetail standard among manufacturers that I can use dovetail scope rings from one manufacturer to mount on another manufacturer's scope base/mount?
