This year, I was curious to see at what distance I was really shooting at waterfowl, including geese.. I borrowed a laser range finder from a friend and was shocked to see what geese look like at 100 yards, 200 yards, and the like.. I also figured out that the decoys around our blind, the ones that were set the furthest out, were well within gun range at a mere 35 yards out.
Once I figured out what the birds looked like at the distances they were actually at, it gave me an idea about what kind of lead I should be giving them and my shot effectiveness actually went up. There were few birds that decoyed within range that got away unless I had only enough time for a "snap shot".
