When me and my friend plays there is often a tendency that when I press Y to reload I fire on my friends screen (very often after we freshly log into a server) I can spam Y and eventually it will click on his screen after 5 or so reload(shots) are fired. This eventually leads to the whole "bullets not registering" thingy.   And yesterday when I played I picked up an usg45, I already had an AK and when I switched between them the bullets would often not register either, I once held the usg45 on my friends screen when actually I held the ak on mine.  It often did not register bullets also after I had put my usg45 in inventory to fill up mags.   I know that you guys are aware of the magazine/bullets not registering, just wanted to help you know where to look into the reasons behind it maybe :0? I tried to be as specific as I can :)!
