Wildcatting was not altogether futile. Roy Weatherby's line of cartridges were once wildcats, as was the .22/250, .35 Whelen, the .25/06, the .243 and 6mm, the .257 Roberts, and on, and on. Wild claims or no, they were good, useful cartridges and they've lasted. Most of it, though, was just a lot of hot air--but people had fun, and that's what matters. This is, after all, a hobby.
