Seems like you missed the main idea.I second this, especially on turrets... maybe. Being able to police your own brass is a great, plausible idea... If that isn't possible due to game limitations, brass catchers could help but they shouldn't come without issues (as discussed in past posts). My only issue is making things too easy late game. Not having to go out and find brass to melt down might make lazy 7DTD characters and take a bit of the "need" out of the game. The less things that make you say, "I need to go find x" the less challenging the game becomes IMHO.
The idea consists that to facilitate a game to players at a late stage of a game.
Brass cather can be made in the form of difficult available recipe or hight level perk.There is many things to do in game: researching, looting, quests, dungeons etc...
and you know, when you got 44 tourets (as me at base) there is not enough time to be engaged only in brass search ..btw you need to find/harvest lead also.
Anyway it is possible to make brass catcher for special recipe or quests or difficult crafting. it is like a suggestion.
Saw a lot of interested forum members about brass cather.
