So I want to learn to speedrun Borderlands 2, since its my favorite game. One issue I have at the moment is, that I don't know how to set up infinite ammo properly. I can do it with single and double barrled Jakobs shotguns, however with a shotgun that has more barrels I don't succed. I watched tutorials on YouTube and also speedruns, but I can't find my mistake. Some help would be really nice. :)
