Are there any wads with a collection of reloadable weapons?

More specifically like an auto shotgun, grenade launchers, reloadable pistols etc.

Honestly, I can't think of anything besides Brutal Doom. I remember HacX's Uzi has a reloading animation after each burst.

If you know where to look, try Realm667!

There is also Supercharge which tweaks and adds reloading to most of the vanilla arsenal, as well as having a quad-barrel auto-shotgun as a new weapon.
