One thing I forgot to mention was I bought two Burris scopes at the time. One for my varmint rifle and the pistol scope. Both had to be sent back because I could not adjust parallax on either. The adjustments on both objectives had to be regulated. If I remember I had to use the 200 yard setting for 50 yards, or the other way around, been a while.
The varmint scope was so dark I sold it and bought a Loopy. Still going strong.
