As far as i can see from your question you want the drops to only contain weapons that fire projectiles, Guns,rifles and automatic weapons and their respective ammo, So you include in the "static items list" all the weapons and ammo, armoured facemask, armoured chestplate or whatever and make the choice "includeStaticItemListOnly": true,
You can also go to the BetterLoot DATA folder and change the setting in LOOTTABLES list to show "false"

"assets/prefabs/misc/supply drop/supply_drop.prefab":{
"Enabled":false,

That should ensure the drops only contain the items you want , The only way to change the rarity of an item is in the betterloot config list.

These have everything you told me to change in them so that it will have only what i have it set too.

If you can help me put these specific items only into the airdrop:

It would be very helpful 

Thank you!
