If the lines mean different distances, don't worry about that. The trick is, find out where the rifle hits at those lines. Say for instance instead of 150, 200, and 250 lines ... say you try that and it hits at 138, 189, and 220.. for instance. You can still use that information when you shoot long distances as long as you remember the lines. Deer seldom walk out at 200 yards exactly and stand there. So don't worry so much about the lines.

News that scope sells for $149.99 I think. You decide if that is a good price for a used scope. I think it is a little high.
