200rds - 300 AAC Blackout Hornady Subsonic 190gr. Sub-X Ammo Details

Hornady Subsonic 300 AAC Blackout is the solution for shooters looking for a terminally effective round without shoulder pounding recoil or a sonic crack. These premium multi-purpose rounds are loaded with 190gr. Sub-X projectiles featuring Hornady's polymer Flex-Tip. The Flex-Tip is a unique take on polymer-tipped ammo; the purpose of the tip is not only to improve the aerodynamics of the round. The Flex Tip keeps the hollow point clear of debris and facilitates reliable expansion that promotes a quick knockdown. This 300 AAC Blackout generates a muzzle velocity of 1050 fps with a corresponding energy transfer of 465 ft/lbs. This ammo is a blast to shoot, and the low recoil makes it a great choice for shooters of all experience levels. Hornady uses new-production brass casings that are non-corrosive, Boxer-primed, and reloadable.

Being 100% honest about this ammunition.
The BAD: It cycles poorly in a semi auto- AR type rifle/carbine. It does not produce enough gas to fully cycle the action to pick up the next round, in my experience. You will need to hand cycle the action when using it suppressed.
The GOOD: Bullet performance is more than acceptable for common targets. Expansion and penetration is acceptable.
