So I tried using manual reloading on the MG 42 and M60 and I can't get it to work. I would bring the belt of ammo or box of ammo (yes I got the correct ammo) up to the machine gun while it is in reloading state and the ammo belt/box doesn't connect/attach. I have used manual reloading on artillery and it works. So am I doing it wrong or is it broke?
