What would be a good spotting scope for NRA Hi-power? I want to be able to see holes at 300 yards, and it needs to be powerful enough for scoring at 600 yards, so what would be the suggested power and minimum objective diameter? When I'm prone, I like the straight eyepiece, but I know in competition, the spotter usually sits, so would the 45-degree be better? Does anyone have any experience with Alpen, Zhumell, or Barska? I'd like to find something under $300, would love some suggestions on what to get, where to purchase, and where to find a good tripod for it. Thanks!
