Hello all! I have enclosed two pictures of a .54 projectile with a single groove and an open cavity. Quite a few of these have been found along the Texas/Mexico border over the years. Undoubtedly they are for the M1854 Austrian rifle which was .54. The bullet measurements are as follows:
D: .541" or 13.74 mm
L: .929" or 23.64 mm
C: .223" or 5.66 mm
The cavity width measures: .204" or 5.15 mm
Apparently this projectile was first used in the Type I Lenk von Wolfsberg/von Lorenz Gun-cotton cartridge. Why would these projectiles be recovered from the Texas/Mexico border? I’m not really sure why. I do know that the French invaded Mexico during the American Civil War. Was this projectile used by itself without the wooden dowel and gun-cotton?
The other cartridge below is what I believe to be a .54 Austrian Multi-Ball cartridge. Can anyone confirm this and the dates that they were used?
