The only thing "pointless" concerning what you conveyed (although... "silly" would be a more appropriate adjective) is the notion of engaging something/anything at the distances of 50 to 75 yards with a 8" SBS. Sorry... but that's....
Okay, you're relatively new here so I'll try and play nice... and not slander you. Sure, you can go to the firing range and have fun trying to hit targets out at those distances with a SBS... but don't expect any of the veterans firing to your left and right NOT to chuckle.
As hogdog mentioned, "...if you can afford one, why not?"
