Expensive glass is hard to justify if your are just hunting. I use a cheapy Nikon and it works just fine for a field gun, bang it around and dunk it and still holds zero. wont cry if I lose or break it eventually.
Thats what I thought until I bought a Vortex Viper.
People always say "I am just hunting, I don't need the best glass/rifle" or "Its accurate enough for hunting"
My question is, there is a life on the line here, why wouldn't you want to be as accurate as possible? I understand competitions you need to have the best to compete, but with hunting you need to be accurate as to not wound or lose the animal. I'm not saying go buy a $2,000 dollar scope, but going from $200-$500 dollars is a small jump price wise and a big jump scope wise. Not to mention you can find high quality used scopes for almost half what they cost new.
As for the hard use, I buy Vortex scopes so if I bang it up or run over it with my truck it will be replaced under their warranty. This helps me a lot when shelling out some coin for scopes.
