Resident Evil 2: 15 Tips & Tricks The Game Doesn't Tell You

8. Gunpowder Crafting Gives More Bullets Than Environmental Pickups

Another small note, as bullet amounts found on the ground differ, but combining gunpowders seems to always give you a larger amount of bullets overall.

The recipes in RE2 are as follows (and you can find them in the game, too):

Gunpowder + Gunpowder: Handgun ammo

Gunpowder + High-Grade Gunpowder (Yellow): Shotgun shells

Gunpowder + High-Grade Gunpowder (White): Acid rounds

High-Grade Gunpowder (Yellow) + High-Grade Gunpowder (Yellow): Magnum ammo

High-Grade Gunpowder (White) + High-Grade Gunpowder (White): Submachine gun ammo

It can be very easy to given inventory space to things other than what looks like a paltry, optional crafting item, but stockpile this stuff and get to combining it together. You'll have a sizeable stock of ammo in no time.
