1. Taking a NRA course for the Oregon concealed carry permit years ago in an indoor range. One students goes up on the line and shoots down the cable that moves the target. Claims the gun has a curved barrel causing the bullet to fly up there in some hyperbolic trajectory.
2. Go to Cabela's to browse. Guy asks the clerk for a pump action shotgun as just racking will scare the BG away. Then says if that doesn't work, he wants some blanks to make noise and scare him. Clerk recommends he get some rubber buckshot too. I say - NOOOO! They glare at me, so I go away.
3. Shooting at an indoor range, it has a giant metal clunky thing to hold the target. I decide to shoot one handed with my non-dominant hand for practice. The edge of the metal thing extends over the 'forehead' of the B-27. I hit the edge, the round or fragment zips down the target in a shower of sparks, cutting it as cleanly as a samurai movie. The edges catch fire. The other guys on the range - ask :WOW, what kind of round it that!
It would be a great stopper - cuts you in half and sets the halves on fire.
4. Just remembered this. At an IDPA, about 5 guys dressed like they came from the Leave it to Beaver era and sausage sack holsters arrive. They are shepherded by a guy who is a reverend who bosses them around and tries to boss the SO too! He's an expert. One of his guys gets up. He has a semi with an attached light and laser. He draws on the stage and the light/laser combo falls off his gun and starts to strobe like a disco. Never saw them at another match (good!).
