This has only just happend to me running around in battle on the kilslagen mountain,i had 256 bullets in my spare shown on screen for my AI-76 assault 4 star went to reload and lost 213 but put 43 in clip to use.
Just before this i put a 4 star acog scope on.Before this ive never had a problem as ive never put a scope on this particular gun all of a sudden ive lost ammo on reload hope this helps?
I’ve had a similar situation happen to me on PS4. I dropped a rifle scope and lost my rifle ammo then went back and picked up the rifle scope and the ammo was included in the drop.
Sorry misread what you put.strange that maybe the scope is at fault somehow
