I just got a Mk2, but it has a BSA scope on it, and I don't want to mess with that. I have a Mueller Eradicator in 8.5-25, but I was looking at something else. I notice that there is a 6-24 Crossfire for $99, and was looking at something in the 6-24 range with mildots. I want to practice out to 200, just to get better at reading wind etc. What suggestions would everyone make for a 200 yard 22LR? A RT base or Zee rings, whichever is cheaper, will be used.
