Shotgun Shells

The first ones are Leon's in the Attic (ch04): 4 on the upper level (Chunk uncovers them), 4 behind the wall he smashes and 5 to the north-west; plus the Gallery Corridor warped closet (4); on Insanity, also the Pantry (4) and Filing Storeroom (2) closets. Later: Raccoon City East (ch09), the rubble of the R.P.D. Main Hall balcony (6, ch10), the Raccoon City Center Side Street (10, ch12) and the final Gene Vault (8, ch15).

Ammo for the MSBG 500, the 990-TAC and the W870 Police.

Scrap + Gunpowder (Large) (Leon, ×3)

Leon buys them at the Supply Box for 600 credits per 3 (200 a shell) and sells them for 50. The recipe appears once he owns a shotgun (the Attic MSBG 500), but on Standard there is no Gunpowder until Raccoon City East. Grace doesn't use shotguns.
