Gentlemen, Please help. Leupold 3.5-10x50 or 4.5-14x50? What are the pro's and cons of both? This is going on a custom lightweight .340wby. This last season I was hunting in the timber,had a 3-9 scope on and I actually needed to turn it up to 9 to make the shot. I just couldn't make out the elk and brush well enough on the lower power. At 9 I could see clearly my shooting lane, but I could have used more magnification I think. I've never had that problem before. I was all set on the 3-9 or 3-10 power but now I'm wondering if I should step up. Shooting ranges from 20yds to 600yds with this rifle. Also I need to think about ruggedness because of the rifle. I need a very tough scope as I've had two scopes fail on this rifle already. I'm also considering a Schmidt & Bender 3-12x50 because of their reputation for being stout. What do you guys think?
