Product Description
Performance Overview
Muzzle Velocity: 1,000 FPS
Muzzle Energy: 489 FT-LBS
The 220 gr HPBT Match Subsonic was developed as a precision-focused alternative to conventional .300 Blackout range ammunition. The objective was straightforward: produce a subsonic load capable of maintaining a high level of accuracy and consistency across a broad range of barrel lengths and twist rates without the cost associated with premium expanding projectiles.
The load is optimized primarily for 5.5"–12.5" barrels, with a nominal muzzle velocity of approximately 1,000 FPS. Longer barrels may produce supersonic velocities depending on barrel length and environmental conditions. It may be pushing supersonic velocities in barrels longer than 12.5" but it's not a certain thing.
With subsonic rifle competition becoming increasingly common, this load occupies a deliberate position in the Phantom lineup. It provides a higher-performance option than our economical range and plinking ammunition while remaining substantially more cost-effective than our expanding and fracturing projectiles. The emphasis is on precision, consistency, and predictable external ballistic performance rather than terminal effect.
The 220 gr HPBT is a non-expanding match projectile and should not be treated as a terminal-performance load. We do not recommend it for hunting applications where reliable expansion or significant tissue disruption is required.
