Sometimes we hit things that we can't even see, like the time I shot at a woodchuck that was about 600 yards away and about 200 feet lower than me. It was a gray day and I was shooting at a woodchuck standing on his mound. Yeah it was "pray" shot. Funny thing, though, when I fired, I saw a bright blue flash, just about where I was aiming with my 2.5X Weaver atop the .30-06 Savage. Then, I said to myself..."Hey SELF! Woodchuck don't flash when you hit them!!! Just then, the 60 cycle hum of a high-tension line caught up with me and a 33,000 volt power line parted and hit the ground. For a few brief moments, electricity arced across the wet ground, then the milking machines in the barn behind us became eerily became silent. The farmer was very cordial about the whole thing, as we'd hunted chucks on his land often and never had a problem before.
The power company's foreman wasn't quite so jolly and he threatened to bill me for the act, but that never happened. Funny, but that line has been discontinued for many years...and the poles removed. However, I don't hunt/shoot woodchucks much anymore, just the ones that invade my house-lot.
