20rds – 450 Bushmaster Hornady Subsonic 395gr. Sub-X Ammo

Hornady Ammunition 395 Grain Polymer Tipped Ammo Details

This 450 Bushmaster round from Hornady’s Subsonic line of ammunition serves as an interesting demonstration in ballistics. Its muzzle velocity is about the same as that of a 22 LR at 1,050 fps (from a 24” barrel), yet its ten times heavier bullet accordingly carries ten times greater energy. Neat!

This is the round to choose when you’re hunting with a suppressor, but it still noticeably dampens sound and flash signatures without a can. Its 395 grain Sub-X bullet is designed to deliver shocking terminal expansion following impact at velocities as low as 900 fps – in this case 241 yards, by our math. The Sub-X achieves this thanks to its supple Flex Tip which wedges into its underlying nose cavity to spread the bullet outward.

This round’s bullet further features a crimping cannelure to prevent setback in a semi-auto, which along with its InterLock ring further helps the notched jacket remain firmly rooted to the core for superior weight retention during penetration. To cap things off, a boat tail to keep downrange velocities faster and the Sub-X itself more potent!

Hornady’s Subsonic ammo is brass cased for even better functionality in a semi-auto. Each round’s low flash powder comes to life at the command of a very sensitive and non-corrosive Boxer primer, giving you a reliable solution for crepuscular hunting.
