I find this more fun in systems like Shadowrun where I can be like 'This mag is alternatively loaded with Exex and APDS ammo and it's for the big emergencies that sometimes happen'. Like, you might have 6 different mags with different ammo in that game and use them all, depending on what situations come up.

I really like Fabula Ultimas take on this too: Basic consumables like arrows aren't limited or tracked, but you have inventory points that inform how many potions or other situation-changing items you can produce out of your bag of tricks, before you need to hit a town to restock. And then they have some abilities/classes you can pick give you more of these points, refill these points in combat or during travel, or key off of these points to do other things related to crafting and item use. Really really good.
