Re: A little about what the new guy wants help with, Thanks!
I would look at one of the Swarovski or Kahles with a TDS reticle. I have a 3-9x Kahles on a 300 WSM. Used off ebay for $400. Crystal clear glass and rugged. We have a 300 hart with a 6-18x Swarovski that goes to 900 with no clicking.
With a 200 yard zero at 9x, the stadias are on at 300, 377, 488 and 604. Drop the power to 6x and they are 327, 472, 592 and 708.
That is a quick and clean system at the distances you are talking. you will need accurate MV (chrono), cheap PDA and the exbal program ($60) and you can run different charts for any elevation and temp for your stadias.
find a TDS reticle scope and look at it.
