So my first real test was at the 200 yard range at Talon. I didn't do it prone, too many other shooters and I dislike hot brass down my neck.
From the bench using a sandbag with the red dot and the Matech iron sight I was pretty comparable. My groups were around 10", with most of the spread being windage. I will need to get a spotting scope I can use when prone, or a shooting buddy.
Task is seeming not as hard as I thought, especially if I am shooting for a 18" gong. Of course none of us are sure what Razzman has in mind.
