No one on the CheapAmmo.com team would ever dream of breaking into our customers’ houses. That’s not just because we’re all decent, God-fearing and law-abiding citizens who respect the sanctity of private property. It’s also because our customers can order Hornady’s 300 AAC Blackout 190 grain Sub-X ammunition!

This ammo is subsonic, and therefore optimal for suppressed firearms (but still compatible with rifles that aren’t equipped with suppressors). The heavy 190 grain bullet’s 1,050 fps muzzle velocity out of Horandy’s 16” test barrel is substantially lower than the speed of sound, so you’re going to get that quiet report which won’t demolish your eardrums if you ever have to fire indoors.

The Sub-X is essentially a massive jacketed hollow point with a polymer column that sits flush with the rim of its jacket. The Flex Tip prevents the Sub-X’s nose cavity from losing its capacity to trigger terminal expansion as a result of obstructing with debris, such as fabric. The Flex Tip also wedges into the Sub-X’s nose cavity during penetration to help promote wide expansion following impact velocities as low as 900 fps. And because the Sub-X’s jacket is mechanically locked to its core in two separate places, it boasts the durability it needs to penetrate to an effective depth for defensive applications.

This ammo is loaded in Nebraska with reusable brass cases, noncorrosive Boxer primers, and propellant that burns up super clean. Order today and your ideal 300 BLK home defense ammo will be right on its way!
