i checked many gun sights for a weight difference,it does stand to reason a short action rifle could be a few ounces lighter,though no company's state that.i do know where you are coming from on every ounce counts,im an avid firearms collector and hunter,as i get older i notice the lighter rifles frequenting the woods with me more often then the big heavy ones.the days of the 20 inch scopes with 4" sunshade on it seem to have dropped to the 2to7 and 1.5 to 4s.being that i am so into firearms,when the 300 wsm was introduced i studied it for some time.after all the hype(comes with most new chamberings)the differences were smaller then most seem to think,i have however found that some long action bolt guns can be harder to mount just any scope on without getting mounts that hang over the bolt.where the shorts seem to fit any.that was the biggest thing i ever found.both exceptional rifles,i would not lean to either one more then the other. lots of guys will use the ammo is harder to get for one(wsm) then the other ,if your typing on the internet then you can get the ammo for either.
