OH god i lol'd but sir these are shells Red ones are Birdshots i believe and the greens are more aggressive types i think these are dragonbreath shells
Shell casings are colored differently by each manufacturer. For example Remington uses green for their basic 12 gauge rounds, while Winchester uses red. It's quite likely that this particular girl is using Winchester's 00 buckshot and Remington's rifled slugs for the purposes of fast identification.
