The part I don't understand is the cartridge conversion cylinders for the replica BP revolvers so popular in SASS. You can buy the cap and ball revolver made by __________ (insert your favorite Italian name) from Midway, and on the same page buy the cartridge conversion cylinder that drops right in. It takes rounds readily manufactured in the US. I'm not complaining that someone has found a loop hole, but why do we all have to carry some form of a lisence, or incurr extra expense to receive a double made in the early teens? Does this law mean I can buy an 8 guage made in 1905 and have it shipped directly to me? 8 guage isn't manufactured by anyone in the US that I am aware of.
