Lancaster-

I am very much enjoying this.
I have seen the pinfire cases with 'rifling' in the case for use with bullet in smoothbore shotgun.

I have also seen photographs of the 'trap door' pinfire cases with the little percussion cap door for easy reloading.
This is great stuff for this thread!!

The Gevelot short-case/deep hollow base bullet with powder charge is a new one for me.
Interesting.

Please assist with relevant translation of these terms from the page with catshead bullet image above:

caliber = (Bore or Groove) diameter?
führung = my free translator says 'leadership' Is this chamber diameter? It's the same for metal or paper case...
länge = length
gewicht = weight
stuckzahl = (number of) pieces (per package)?
