About
What it is, and why it matters
The Blaser F3 is a premium German competition over/under shotgun featuring the proprietary Triplex overbored barrel design with an 18.65mm bore diameter and 2.5-degree forcing cone angle for reduced pellet deformation and tighter patterns. The barrel balancer system adds up to 170g of weight under the forend for discipline-specific balance tuning, while all three available barrel lengths are engineered to nearly identical weight through contour adjustments. The F3 features the IBS (Inertia Block System) to prevent doubling, the EBS (Ejection Ball System) for smooth ejection, and a single selective trigger with a crisp 1400g pull. The matte black action with gold F3 logos and HIVIZ interchangeable front sight complete the competition-ready package. Available in Competition, Vantage, SuperSport, and SuperTrap configurations.
The Blaser F3 was the first competition O/U to feature an overbored barrel as standard - the 18.65mm Triplex bore was larger than the industry norm of 18.4mm, providing measurably tighter patterns at all distances. Its barrel balancer system, which allows shooters to add or remove weight under the forend, became one of the most copied features in competition shotgun design.
The F3 is Blaser's flagship competition O/U, in production since 2003. Weight: ~3730-3780g depending on barrel length and configuration. Barrel lengths: 710mm (28"), 760mm (30"), 810mm (32"). Bore: 18.65mm overbored (Triplex design). Chamber: 76mm (3"). Includes 5 Briley extended chokes (SK, IC, M, IM, F). Available in 12, 20, 28 gauge and .410. Left-handed models available. Grade 5+ walnut stock. The SuperTrap variant features a higher rib and adjustable comb for trap-specific sight picture.

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.
