I bugled in my best bull yet last year on opening evening about half hour before dusk. He came out of the reprod screaming at me! He had about 10 cows with him. I had him at 45 yards but he had a small bush covering his vitals. I drew back thinking I would shoot when he cleared the bush but he took off chasing his cows before I had a clear shot. Just my luck. Had another one on the other side of the thick stuff 4 days later but couldn't make it happen. I guess thats why they call it hunting and not shooting right?
