About
What it is, and why it matters
The Baikal MP-133 is a Russian pump-action shotgun manufactured by the Izhevsk Mechanical Plant. Chambered for 12-gauge shells in 70mm, 76mm or 89mm (2.75, 3 or 3.5 inch) lengths, it uses a sliding forend with dual action bars feeding from an under-barrel tubular magazine holding up to four rounds. Known for rugged, inexpensive construction, the MP-133 is widely exported for hunting, sport and security use, with the MP-133K variant fed from a detachable box magazine.
The MP-133 replaced the earlier IZH-81 in Izhevsk's pump-action lineup and became one of Russia's most common civilian repeating shotguns, prized for affordability and the robustness typical of Izhevsk-built firearms.
Exported to the United States as the EAA/Baikal MP-133 and marketed under various Baikal-branded names. Available with interchangeable choke tubes and multiple barrel lengths from 510mm to 750mm.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
