About
What it is, and why it matters
The Baikal MP-151 is a Russian gas-operated semi-automatic 12 gauge shotgun developed in 1998 by the Izhevsk Mechanical Plant. Built on the base of the IZH-81 platform, it featured a manually adjustable gas system intended to let the shooter tune cycling for different loads. Produced only in small numbers around 1999, the manual gas regulation proved unnecessary and the design was quickly superseded by the self-regulating Baikal MP-153 in 2000.
The MP-151 represents the experimental step between Baikal's IZH-81 pump-action lineage and the company's first successful gas-operated self-loader. Its hand-tuned gas valve was an engineering dead end; the self-regulating MP-153 that followed in 2000 became one of the most widely exported Russian sporting shotguns.
A short-lived prototype/limited-production model; its self-adjusting successor, the MP-153, became Baikal's mainstream gas semi-auto shotgun.

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.
