I'm trying to find a better scope for for my 300wsm mountain rifle. I want to keep the total weight under 7.5 lbs. The catalog says this scope weighs in at 13oz which is about as light as I have seen for decent scope with turrets. My max distance would be 600yds. I'm a little concerned about not having a side focus, but that may not be a issue for 600 yds or less. Would this scope make a for a good, lightweight, mid-range scope? If anyone has any better suggestions, I'm open to other options. Thanks!
