Forge & Field Apex HP .2175 30gr Boat Tail Slugs (200 pcs)

Forge & Field Apex HP .2175 30gr Boat Tail (200 PCS) — High-Velocity Precision Hollow Point Boat-Tail Slugs for 5.5mm (.22) PCP Air Rifles
The Forge & Field Apex HP .2175 30gr Boat Tail is the fastest, flattest-shooting entry in Forge & Field’s competition-grade Hollow Point Boat-Tail lineup. Originating from Forge & Field’s acclaimed NRL solid-point boat-tail architecture, the 30-grain (1.94g) Apex HP combines a precision-engineered hollow point cavity with a drag-reducing tapered boat-tail base — making it the ideal choice for 600mm and 700mm high-power 5.5mm (.22) PCP air rifles that want 920–960 FPS flat trajectories without pushing extreme regulator pressures.
Key Performance Advantages:
Tapered Boat-Tail Base: Shrinks the low-pressure turbulent wake behind the projectile, dramatically reducing subsonic base drag and retaining far more downrange velocity and energy at 100m+ than conventional flat-base or cup-base 30gr slugs.
High-Pressure Cold-Swaged Uniformity: Formed under high pressure in precision dies rather than cast, eliminating internal air voids, weight variance, and vertical stringing on 100m benchrest and NRL cards.
Proprietary Lead Alloy & Anti-Fouling Coating: Malleable enough to obturate cleanly into .2175″ (5.524mm) rifling lands for a gas-tight seal and low Extreme Velocity Spread (ES), while the specialized surface coating minimizes barrel leading.
Dual-Purpose Target & Hunting Performance: Delivers pinpoint grouping for NRL22 and 100m benchrest alongside rapid hollow-point expansion for long-range hunting and pest control.
