Craig,
No problems. I help a number of folks getting started at distance.
We all had to get help from someone at one time or another, and we just pass it on when the occasion presents itself
Without getting on the site to remember model #'s, the 4-12 I have would work fine for 600 yard shooting with the set-ups you describe.
I will get specifics to you tomorrow hopefully. smile
