The cattle can be a big help. I have a .22 rifle that I haven't used since I was a teenager. I bought a cheap scope for it and need to sight-in the scope. Yesterday evening, I  set up a board with a paper target about 180 feet from the porch and began taking shots and then looking to see where they hit. The cattle came over to help. They came right over to the target, knocked down the board, and ate the paper target. Since it was getting dark and the cattle were still there, I quit for the night. This morning I set up a larger board with three logs and a new paper target. Before I got off a shot, the cattle came over, knocked down the board and ate the paper target. Below is a picture of some of the cattle at the target. I guess I need to fence in a larger area.
