I'm at a friends house out in a local farming area. We are shooting at groundhogs in a field across the valley. Using a Gamemaster 30 06 ( not the greatest varmint rifle ). No one was coming even close. I took one shot and nailed a groundhog at almost 700 yards. It was just a small black speck moving around in the field. So far away, the end sight covered it when I aimed. I guess luck, but "I was" aiming at the groundhog. Everyone there also said it was luck; and I replied, it would have been luck if I were shooting in the opposite direction. I remember picking up the rifle and saying: Let me show you how it's done. The " you were just lucky" replies faded, when I nailed another at 500 yards. Rangefinders don't lie. I guess I'm just a lucky shot. I kind of felt bad, but we did eat them.
