Does anyone have a factory drawing for the bullet of M193? In particular, I want to confirm the nominal jacket thickness.
Here is a picture from David Hughes book, The History and Development of the M16 Rifle and Its Cartridge.
The thickness is given as 0.021". Same drawing number that Dennis has noted but from Frankford Arsenal.
Note 4 reads: Wall thickness over cylindrical length of bullet.
Thank you very much, all!
