Deep Dive
Overview
This 338 spectre ammo is intended for shooters who need quiet, stable performance for medium-game hunts or controlled target work. The heavy 300-grain MatchKing bullet maintains clean flight at subsonic speeds, which supports precise placement at practical hunting distances. Subsonic operation reduces noise while producing soft recoil that helps maintain control through follow-up shots. The 338 Spectre cartridge performs well in suppressed platforms where accuracy with heavier bullets is a priority. For hunters who want predictable results on medium game with minimal sound signature, this subsonic load offers a balanced option.
History and Development
SBR manufactures the 338 Spectre to provide shooters with a cartridge that delivers reliable subsonic behavior through simple brass forming. The parent case is the 10mm Magnum, which supports efficient reloading with minimal complexity. The cartridge gained popularity for its light recoil with strong accuracy potential on small- to medium-size game. SBR’s approach emphasizes precise assembly with controlled powder charges to maintain subsonic speeds while supporting consistent performance through suppressed rifles.
