Forge & Field Apex HP .2175 36gr Boat Tail Slugs (200 pcs)

Forge & Field Apex HP .2175 36gr Boat Tail (200 PCS) — Verified 0.195 G1 BC Heavy Long-Range Hollow Point Slugs
Built for 700mm Sniper and PRS air rifle platforms, the Forge & Field Apex HP .2175 36gr Boat Tail delivers a verified G1 Ballistic Coefficient of 0.195 — roughly twice the aerodynamic BC of traditional 36-grain flat-base or dish-base airgun slugs. Weighing 36 grains (2.33 grams) with a streamlined 10.53 mm (0.4145″) boat-tail profile, it slices through switchy Highveld crosswinds with just 46 mm (1.8″) of drift at 100 metres (@ 940 FPS in a 15 km/h 90° wind) while delivering a massive 57.1 ft-lbs (77.4 Joules) of retained terminal energy at 100m.
Key Performance Advantages:
Verified 0.195 G1 Ballistic Coefficient: CFD-refined nose ogive and tapered boat tail minimize base drag and keep the projectile rock-solid at 100m to 200m.
Zero-Void Cold-Swaged Construction: High-pressure cold forging ensures identical weight, length, and radial balance across all 200 slugs in the box, eliminating vertical POI shifts.
Unique Malleable Lead Alloy & Coating: Designed specifically for the longer bearing surface of a 10.53 mm slug, allowing 1:16″ rifling lands to engrave cleanly with minimal friction and near-zero barrel leading.
Hard-Hitting Hollow Point Cavity: Combines elite NRL / Benchrest long-range grouping with authoritative downrange expansion.
