does someone knows a source which names the first full metal jacket bullet in history.
With the beginning of smokeless powder like Cordite, NC or Poudre B the muzzle velocity of the bullets increases. So the normal lead bullets couldn`t take up the forces of the twist. The bullets needed a jacket for the new generation of propellants.
I think the first FMJ should developed in the age of around 1880.
Does someone knows the first rifle caliber with FMJ bullet design and the inventor?
Thanks for any help.
