45 acp FA 42


I have a 45 acp FA 42 headstamp that is identical to Figure 25 on page 29 of th History of Modern US Military Small Arms Ammunition Volume II.
My round has no star at the 3 o’clock position. The F A 42 are in same positions as in picture on page 29.
GM primer and GMCS blt.
Can anyone tell me about this. Was the star ground of the bunter and used ror regular ball ammo or something else?
