FX foxes at 50 meters

Golf balls are fun for target practice. Amazing how far they can fly when hit well. One can discern how well they hit the golf ball by it's trajectory. :)
I have a 50 yd range that I can shoot off a bench in my shop. I have two orange painted golf balls drilled through and hung on a tree with a coat hanger. I have noticed the very thing you said you can tell where you hit the golf ball just by where it goes.
