In all fairness, the original question from FReeper Verbosus was about 12-gauge shotgun shells but even though I would LOVE to fire one of these 155mm shells, whether a smoker or any other, the notion of its age causing it to rupture the barrel would tend to give me pause.....I’ve heard that large pieces of shrapnel can be difficult to remove from certain body regions....
I’m usually not the “hold muh beer an’ watch this!” sort of guy, as witnessed by my full original complement of fingers and no major scarring ;-)
