Ok, you guys did so well on the 106mm Recoiless, let’s move on to the 75mm Recoiless
I have case with “SHELL M309” stenciled on the base of it. What loading is this? There is no impressed case type information.
Stenciled on a 75MM M31A1 case is "SHELL HE???E21. What is missing and what loading is it?
Anyone have a manual for the ammunition types?
