I got a couple of boxes of the 44 cookie cutter ammo when it first came out.
I guess it never occurred to me it might be illegal.
Kind of a moot point however as I discovered it would not shoot well or anywhere near regular ammo.
The fact the bullets weigh half what a normal slug would and are more than likely much smaller
in diameter than the revolvers of the era's throats caused me to just give up on them.
They might actually shoot well thru a newer gun but I still don't want
to have to fool with the radical sight adjustment.
If I wanted to shoot a solid copper bullet, I would probably go with something like this:
or one of the Barnes numbers.
