I'll bet they were a bear in combat. Can you imagine cleaning one under field conditions?
Lets see old chap, shall we use Tide or Rinso?
The cartridge cases looked flaky to me, no pun intended, they were rolled brass. You can buy modern formed cases now for them.
Did you ever use the 40mm Grenade launcher on the M-16? that was a hoot to. You could shoot it and make a sight correction and fire again and almost beat the first shot to the target. When I shot for qualification we only got two shots, they were short on ammo.
Thats almost as brilliant as when we ran out of Standard fins for bombs and had to use High Drag Fins wired shut at the cost of $4000 for every mission we flew.
Best wishes, Bill
