hey folks, what would the opinion of you all be regarding a cheaper scope on a .30-06? Unfortunately, I don't have much cash to spend. I inherited an .30-06 from my grandpa. It has an older scope on it "SPF Aquarius" 3-9x. The current scope/rifle combo is killer, but I was informed by a friend's father that the o-rings have dried up on it and the nitrogen has probably leaked out. Anyhow, this will be my first year hunting and I know a scope without gas purging is going to fog up quick. I am looking to spend around 300.00. Do any of you know whether a Vortex Diamondback would hold up to the 06's recoil? Any other suggestions would be great. Although it doesn't seem like too many folks on here dabble with 300.00 scopes (those damn USO's, PST's and Leupold Mark 4's make a man drool...) Any input, as always, is greatly appreciated!
