So, what do you think these may have been made for?
Parent case; 32 Long Colt
OAL; 0.919", I think un-trimmed because of the factory like finish on mouth.
Neck length; 0.235".
Mouth ID; 0.254"
Case body straight and undisturbed at 0.317".
Appear to have been annealed.
Brass is totally clean inside, so never actually fired after forming.
