2Poppa, that rifle is a Browning 7mm mag. It sure does look like a black powder gun in the picture, though, but it's just shadows cast by the camera flash.

As for story, I spotted an unidentified deer coming out of the treeline about half a mile away on a neighboring farm. I glassed it and it looked like a respectable buck. After crawling along a ditch and wiggling through the grass for half an hour or so, I got to within 200 yards of him. At the shot, he collapsed on the spot.
