— In-game description
12x70 Buckshot (sometimes simply called Shotgun shells) are makeshift shotgun shells containing buckshot.
Buckshot ammo is usually found in collections of shells on the bodies of most dead Metro dwellers, especially Communists and Nazis, and in their weapons. In early chapters of Metro 2033 shells can also be found on dead Bandits. Buckshot can first be bought at the Riga kiosk in 2033. 1 MGR buys 2 Rounds whilst 4 Shells will buy 1 MGR. In Metro 2033, the 12x70mm Buckshot are red shells, but in Metro: Last Light and Redux version they are blue, suggesting possible different types of 12 Gauge shells, the buckshot seems to be homemade as stated in the description, but still capable of doing the job. The shells have short effective range but high stopping power, optimal for combating most types of mutants at close, but capable of killing even heavily armored enemies at close range. With the extended barrel attachment for shotguns, they are more useful at medium range but are still inferior at long range. You can carry up to 120 shells in reserve in Last Lights. In Last Light's Ranger Hardcore mode, you can carry a maximum of 56 shells only, furthermore, each pickup gives you a minimum number of shells.
Shotgun shells return in Metro Exodus as the only type of ammunition for the Ashot and Shambler. This time, their casings are again red, same as in Metro 2033. The player can only carry 24 shells by default and 48 shells with upgraded Carrier vest. They are especially effective against mutants, but aren't usually a viable option against human enemies, as long-range combat is much more common in Metro Exodus, given the abundance of open areas. Shotgun shells can be crafted at a workbench, 6 rounds cost 16 mechanical and 6 chemical materials to produce.
