Product Overview
Hornady 190-grain Sub-X is an expanding .300 Blackout subsonic load made for medium game and personal defense. The Sub-X carries a polymer tip over a lead core and is built to open at subsonic speed. It leaves the muzzle at 1,050 fps with 465 ft-lbs and has a G1 BC of .437.
Zeroed at 50 yards, it drops 6.8 inches at 100 yards. From a 100-yard zero it drops 33.4 inches by 200. Subsonic at the muzzle, it leaves a suppressor no sonic crack to deal with.
If you're cross-shopping, Sellier & Bellot's 200-grain Subsonic FMJ is a plain closed jacket 10 fps faster on a higher G1 BC of .558. Ammo Inc's 220-grain Stelth is the heaviest subsonic bullet compared, with 95 ft-lbs more at the muzzle.
- The only subsonic .300 Blackout load compared that is built to expand
- Less drop at 100 yards from a 50-yard zero than both 208-grain subsonic loads compared
- Still moving at 955 fps at 200 yards
- The least muzzle energy of the subsonic loads compared, at 465 ft-lbs, 34 behind Sellier & Bellot's 200-grain Subsonic FMJ
- A lead core, so it is out where lead-free ammunition is required, and no subsonic load in the caliber uses a copper bullet
