Although this was likely intended for blanks, when I loaded the cylinder with 22 shorts ... here's what it did .... 8 hits out of 18 shots at 50 feet. - -all key-holes - -
The cylinder bore was about 1/8" longer than the case length of a 22 short, with the bullet unsupported into the 45 bore of the cylinder. A very impressive little muzzle flash. A fun addition to my toys.
