My mistake did not result in a missed elk but the worry was with me for a couple of days.

Propped my rifle up in the corner of a large Cabela tent before going to sleep. Tremendous winds came down the valley whipping the tent and knocking the rifle to the ground during the night. An earlier hunted had missed a large elk when his turrets had been moved while riding with the rifle in a scabbard. The elk I ultimately killed was the one he had missed on his hunt.
