About
What it is, and why it matters
The Boito Reuna is a Brazilian break-action single-shot shotgun manufactured by E.R. Amantino under the Boito brand. Built around an external-hammer boxlock action with an automatic extractor, brass bead sight and a fixed full choke, it is an affordable, robust shotgun aimed at small-game hunting, pest control and entry-level shooters. The .410 bore model is chambered for 3-inch magnum shells and fitted with a hardwood sporter stock.
Boito is one of Brazil's oldest sporting-arms makers; the Reuna is its long-running budget single-barrel shotgun, widely sold across South America, Europe and Australia as a no-frills hunting and utility gun.
Offered in several gauges including 12, 16, 20, 24, 28 and .410. Barrel lengths vary by market, typically 26 or 28 inches. Also exported under various importer names.

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.
