So what does each tag do?

For example what does the SHOT tag on say the 00 shotgun ammo actually do.

I think the shot tag ignores any hard to shoot tags. Like smoker zombies and skeletons have hard to shoot, so a rifle might take several shots to actually hit one of them, but the shotgun’s ammo will blast them apart with no care to their hard to shoot ability.

All I know is that in my experience it does not mean that the ammo launches multiple projectiles.

The projectile acts like a cloud of projectiles in some ways but not in others.

Okay so is it possible to have the reload one tag on magazines and does that carry over to the weapon it is loaded inside?
