This high-performance 220 grain subsonic is built entirely from premium, match-grade components and is manufactured to strict tolerances. It combines excellent (MOA) accuracy with maximum payload! This round is also free of harmful fillers which tend to clog suppressors.

This ammunition revolutionizes subsonic hunting in the .300 Winchester Magnum caliber. In the past, the terminal ballistics of subsonic ammunition, including the .300 WIN MAG, have been limited in respect to knock down power and wound channel size by projectiles which did not expand. Engel Ballistic Research’s new .300 Winchester Magnum "Max" Subsonic Expander maximizes the transfer of energy on live targets exponentially by utilizing a projectile which dramatically and rapidly expands on impact with soft tissue creating a large cavitation while at the same time cutting through live tissue in a way similar to a broad head on an arrow.
