I've probably answered my own question, but how big a risk would shooting into a pond cattle drink from pose?
My buddies and I do a lot of .22 plinking, and we had the idea to sink a couple model boats on a pasture pond. It's a roughly 65 acre pasture with 3 old CCC retention ponds and an automatic tank so it isn't the only watering spot, and it's one of 3 pastures in rotation. The pond is about 30 foot in diameter and maybe 3-4' deep until late summer. I'm guessing a couple dozen bullets is probably a negligible amount, but I'm leaning towards not risking any contamination at all, just to be safe. Anybody have better insight?
