well, guess what, here's a story for you:
my young sons and I were out on a hunting and exploring venture. We were along ways away from home in the SE corner of the prov, had an NEF single shot rifle, was brand new, and had been sited in, a shot was fired out there, spent case jammed in the chamber, nothing to get it out with, MacGyver saw the antenna on the Dodge crew cab fender, said there is our cleaning rod, tried to slide the muzzle down on the antenna, the ball on the antenna end was too big, we always carry tools, cut the ball off, tried again, worked like slick, poked out the jammed case, day saved, carried on. We had tons of parts vehicles, but that antenna was never replaced, drove that truck for years after that, radio worked, but wasn't 100 % without the ball!
