About
What it is, and why it matters
The Caesar Guerini Apex is an Italian over-and-under break-action field shotgun built in Brescia and offered in 12, 20, and 28 gauge with 3-inch chambers. Designed as a light, well-balanced bird gun, it pairs a hand-polished coin-finish boxlock receiver protected by Guerini's Invisalloy coating with a Turkish Circassian walnut stock in a Prince of Wales grip. It features a single selective trigger, automatic ejectors, five flush-fitting interchangeable choke tubes, a rounded fore-end, and full-coverage hand engraving.
Caesar Guerini was founded in 2002 by brothers Giorgio and Antonio Guerini, and the Apex sits at the top of the company's dedicated field-gun range, distinguished by four different hand-engraving techniques applied across the full receiver.
Average factory weights are roughly 7 lb in 12 gauge, 6 lb 10 oz in 20 gauge, and 6 lb 5 oz in 28 gauge. A manual safety is standard with an automatic safety available as an option.

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.
