What constitutes a reasonable amount of firepower for a private citizen to possess is a hot button issue right now in America, and judging by the impassioned, dug-in arguments from both sides of the aisle, it will continue to be a controversial subject for a long time to come.
Here’s something that should be fairly uncontroversial, however: it is not strictly necessary to blow apart a few bowling balls in order to find out what material they are made out of. In an effort that requires no bullets whatsoever, you could mosey on over to Wikipedia of all places, to find out that the predominant material used in bowling balls today is one of a number of proprietary resin blends derived from polyurethane.
Or you could annihilate a couple of the fucking things with an elephant gun. Your call!
