About
What it is, and why it matters
The CBC Pump 12 is a Brazilian pump-action shotgun developed by Companhia Brasileira de Cartuchos for military, law enforcement, and civilian markets. Chambered in 12 gauge with a 70mm (and 3-inch magnum-capable) chamber, it feeds from a tubular magazine holding six to seven rounds depending on barrel length. The design uses an aluminum receiver with integrated Picatinny rails, a six-position adjustable polymer stock with an internal shock-absorption system that cuts felt recoil by roughly half, and ghost-ring sights. Offered with 14-inch, 19-inch, and 24-inch cylinder-choke barrels, it accepts standard buckshot, slug, and less-lethal anti-riot loads.
CBC, founded in 1926 and Brazil's dominant ammunition maker (parent of the Magtech and Sellier & Bellot brands), expanded into tactical long guns with the Pump 12, positioning it as a domestically produced alternative to imported combat shotguns for Brazilian security forces.
Also marketed as the Taurus ST-12; earlier development examples were shown as the CBC Pump Tactical. Publicly displayed at the 2017 LAAD Defence & Security exhibition in Rio de Janeiro.

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.
