Loading 10mm Auto that I shot in a Glock M20. Using a Dillion SDB and for whatever reason one made it through without powder. Shooting slowly, thank goodness and squibed one. Instead of doing the right thing and getting out a brass rod and driving the bullet out I came up with the bright idea of loading up a bulletless case with a minimum amount of powder and shooting out the bullet... which I did with my arms stretched around a tree. Seemed to work fine. Next time I cleaned the gun I found the bulge in the barrel. A trip to Glock and and a couple hundred later all was well with a new barrel. Lesson learned the expensive way.
