My plan was to do this with a 10mm Glock 20, but on the first pour I had some technical difficulties with my "mystery metal" dropping a bit too large out of this mold. My old man, however, wanted to feed some to a 38-.40 lever gun, and so cast them out of 20-1. THOSE fell out exactly where we'd expect them to be. Ran the first ten over the chronograph and got an average of 1357 fps, and then turned them to the rows of milk jugs:
130341
130340
It took four one-gallon jugs to stop them, and they hit the back wall hard enough to dent the fifth. Expansion (measured by wooden ruler) is an honest 9/16th's of an inch. The neat thing is that they didn't round over AT ALL - it's just a nice, flat tabletop of doom. Blows them up nicely!
