A rusty, pitted bore black powder era H&R top break .38 S&W. This one had a barrel cylinder gap that you could read a newspaper through, (Seriously!). I shot it with smokeless, (not recommended), very light loads, (A 148 with 2 grains of Bullseye). Velocity ran about 450 fps. and would stick in a block of hemlock with about a half of the bullet showing. A real powerhouse! I ground a flat washer down to close up th cylinder gap and mig welded it in place. (not recommended either). I picked up 60 fps!. Now we were making real horsepower, a little over 500 fps. A little front sight filing, and I even used it to dispatch a few chipmunks that were cleaning out the bird feeders daily. I eventually came to my senses and stripped it and welded the barrel from both ends. I now have a much nicer one with a good bore that shoots about half as well as the beater. Go figure. This was the worst junker, but also, strangely one of the more fun.
