Here's the deal on the parallax issue- I have had several people dismiss parallax as a factor in longer range shooting, and I could never see why. To me, it's just another way to tweak accuracy at little expense, no extra weight or technology.
I have taken to sending my Leupold scopes back to the factory to be parallax adjusted at 400 yards, and they come back with little parallax at any normal range. I have been dissappointed in how much parallax they have straight from the factory.
So, in short, it was more of a question to see if I was wrong about the importance of parallax and if someone could demonstrate that fact.
