Not the best shooting I've ever done, but you'll see the enjoyment that was had.
Target was a 55 gallon drum lid at 200 yards. Gun is a bone stock Ruger 10/22 carbine, except a Primary Arms 1x red dot and a thumbhole stock. Shooting subsonic ammo (no can), my friend and I discovered it was easy to hear the bullet impact on the can lid, and there was a perceptible delay. This morphed into a competition of sorts - who could get the most number of impacts on target before hearing the ring of the first one. My buddy managed 4, this is me hitting 5:

Edit - if you listen close, you can hear the thuds of the impact, first one is about 1ms after the last shot goes.
