Re: 22x enough for 1000yards?
I have two NF 5.5-22x50s and love them. I was banging a 4" popper at 1,000 yesterday using one on my 6.5-284.
Last weekend, I shot an F-class match and there was almost no mirage until the very end of the match. I could see the "X" in the x-ring at 1k, and all of the scoring rings, and so could effectively could quarter the 5" X-ring well enough to be confident at 800, 900, 1000 yards. Still didn't win, but could see the target fine.
The beatings will continue until morale improves.
