Really Good Win Primer
Was unloading the clothes washer into the dryer and heard a metallic sound in the washer (who hasn't washed some change) but found it was a Winchester large pistol primer, unfired. So, of course I had to try it, right? Went bang just like its supposed to! Wash, rinse, spin dry, fabric softener, and rinse and it still went bang. Way to go Winchester!
