About
What it is, and why it matters
The CBC 151 is a Brazilian single-shot, break-action shotgun produced by Companhia Brasileira de Cartuchos (CBC). Built around a simple top-break action with an exposed hammer and a single smoothbore barrel, it was an inexpensive utility and hunting shotgun chambered for 12 gauge (as well as 20 gauge and .410 bore in other variants). Widely exported and sold under numerous importer brand names in North America, including Magtech and K-Mart store labels.
Sold under many private-label names over its production life, including the K-Mart Model 151 and through importers such as Magtech and Firearms Import and Export Corporation (FIE). Closely related to the CBC Model SB single-barrel series.

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.
