Sharpsman: That is STUNNING accuracy!
I am an amateur when it comes to knowledge of Bench Rest "secrets" but have attended MANY BR Matches as an observer and found them fascinating and intriguing.
I am assuming your "silver dollar" sized groups were shot on your chosen times conditions (no wind, mirage etc).
Again good for you and thanks for your observations on the 6m/m Dasher - very interesting.
I would call that "absolute accuracy" (silver dollar sized 10 shot groups at 1,000 yards)!
Hold into the wind
