Okay, after my last video I traced my issues to either ammo or the chamber of my gun, I now believe it was all ammo related. The magazine plays a part to, and the mags are clearly easy to damage, but I think this shows how the gun should run. The Prvi Partizan ammo I'm using doesn't have the same oomph as the original loads, so new/old ammo will be tried next.
