Plinking is the most fun but I use mine for paper most of the time. There's just no place to plink around my area.
When I went to visit my sister in IL., my brother-in-law took me (and my guns) to a gun range/dirt bike trail. They had the standard ranges for rifle, pistol and shotgun, but they also what they called the plinking pit. It was a large pit with misc. stuff in there. You were allowed to throw anything you wanted in there as long as it wasn't glass or metal. We spent about 2000 rounds of .22, 500 rounds of .308, an unknown number of misc. handgun calibers and half the day at the pit. Dusk, extreme hunger and a lack of ammunition drove us from the pit. It was a great time.
