My old man took us kids out to a waterfront facility one day and we spent an hour or two shooting at some soft yellow-pine boards backed by an enormous, 100-foot-high, 100-yard-long pile of clamshells dredged up for use as road metal (standard roadbuilding material in south Louisiana 50 years ago, still is).
He made sure we understood what the effects we were seeing on those 2x6" pine boards would equate to, if a person were ever struck by one of those little 40-grain soft-lead bullets fired by his old .22-cal. autopistol.
I took 15 young men from church to the range. They fired the Ruger MKII (.22LR), S&W 686+ (127 gr 38SPL), Magnum Research BFR revolver (45-70 405 gr "cowboy" loads) and Ruger SuperRedhawk .454 Casull 7.5" bbl (200 gr FMJ @2000 fps). The kids had a blast (literally). All of them had prior experience shooting rifles. Few of them had any handgun experience. That was the objective of the trip. It was a long night cleaning :-)
