To make throwable/tnt guns, you need a procedure.
Go in the Ranged Item's Triggers, and click on the plus next to (When bullet hits block)/(When bullet hits player)/(When bullet hits living entity) or (While bullet flying tick) for I THINK that makes tnt explodes in the air.
Then in the Procedure, put the "Spawn at x: (x) (y) (z) living entity: [Ageable entity]
Switch [Abeable entity] with [TNT]
Thats how you make Throwable/Gun TNTs!
