I don't do long range shooting so cannot comment on that aspect.
But, I shot competitively for years, and won consistently, using a $3.00 garage sale discard. I think it was a Tasco.
I bought a Simmons new (only scope I have ever bought new) for my wife's .243. Excellent, I can't see why more than $100.00 should be spent on a scope.
My first hunting trip ever with a scoped rifle, the sling swivel broke and the scope smashed on rocks. That can happen to a $50.00 scope or a $5,000.00 one.
My current scopes are all garage sale discards and they suit me just fine.
