Back in the 1980's I was hunting bear on the Mogollon Rim. I had shot one, and when I was climbing back up the cliff face, I decided to take a short cut and try to climb from tree to tree, bad idea. My rifle sling got tangled in the limbs and branches, and after several minutes of hopelessly trying to free it, I found myself in a situation where I was either going to fall 75 or 100 feet to my death on the rocks, or let my rifle go. I let the rifle fall.
It was a Remington 700 ADL, the old wooden stock, with a Leupold 3x9x40, and Burris Zee rings on it. It landed on the butt, and then tumbled down the rock slide. When I climbed back down to retrieve it, the objective bell was bent down some, not the tube, just the over hand in front of the lens. The stock didn't suffer any breakage, just deep scratches.
Anyway, when I took it out to the range to check everything out, it was only 3" off zero at 200 yds., I couldn't hardly believe it.
Since that incident, I haven't given much thought to carrying or lifting my rifle by the scope tube.
