I have nice Kimber .243 with a Leupold 3x9 scope. They state it has a match action and barrel ? It's plenty accurate at 2-300 yards. Anyway I want to up grade the scope to something that will be more long range. I realize there is only so much you can do with a light bullet .The question is what scope power is enough and which scope would be best for this rifle? I'm thinking Vortex Viper HS 4-16x44 with dead hold reticle. Good for coyotes, deer, etc. What's your opinions?
