Trying to create a new bow that takes existing ammo types

Yes, that works. I am having a slightly different problem now, however. I have made child classes for PrimalItem_WeaponBow and WeapBow (I want to modify the damage). I have set the weapon template in my child version of PrimalItem_WeaponBow to be the child version of WeapBow. This doesn’t seem to work though, because any modifications I make to my child WeapBow aren’t happening in-game. I looked at the stone arrow and it has these entries for ‘Ammo Support Drag Onto Weapon Item Weapon Templates’, and I think that the entry there of WeapBow is making it so my child version doesn’t get used. Any ideas on that? Hopefully this makes sense!
