I have never seen one and would not like to shoot it a 357 from a derringer is a brute and nut something I would shoot for enjoyment and that thing would be worse and I don't think it would even be controllable
At close range with a neck like a 223 i think considerably more. ?? Experts please advise or speculate.
Haha, it's a joke mate, but it would have very low muzzle velocity all the same. No idea where abouts though. Pretty sure demolition ranch did a video featuring them.
fyi about 1000-1200fps ballpark for the 223 i think. wouldnt mind the 410/45 to go with my bond arms derringer but there isnt any in oz as far as i know
