Once I had a big sand pit as a backstop, I hunged 1/2 dozen tennis balls on strings, all at different higths, that way I never shot the same target twice and if I hit I would have 2 or 3 shots at a moving target, I never shot so well as I did in those days, ......my shooting today that I have a regular target is way inferior than than.
pluss I could shoot a hge number of arrow in a raw without having to worrie about busting knocks
