308 Win – 190gr Subsonic REX – 20 Rounds

Product Overview

Looking for the best .308 subsonic ammo? Our .308 Winchester 190-grain subsonic REX ammunition delivers unbeatable stopping power for shooters and hunters.

Our 190-grain subsonic REX round offers superior accuracy and quieter shots, making it ideal for use in suppressed firearms.

The heavy bullet combined with a low muzzle velocity ensures consistent performance, and the high ballistic coefficient (.515) helps maintain trajectory over long distances.

Due to this round being a heavier subsonic round, it requires a barrel with a 1:10 twist rate or faster.
