Atomic's 300 Blackout Subsonic Match Grade ammunition features a hollow point boatatil bullet and has low recoil.

Atomic Ammunition's 300 Blackout 220 grain Sierra HPBT match king loaded in new brass is made with only the very best components available, such as new, reloadable brass cases, Hodgdon powder and Sierra's world famous MatchKing hollow point boat tail bullets. Atomic Ammunition's newest product, our 300 Blackout is unlike most high powered rifle ammunition. It is quieter, has less felt recoil, produces the same energy and power as many 45 ACP police and military service rounds yet delivers excellent accuracy past 100 yd from rifles with barrel twist rates of 1:8 inches or faster. This specialty ammunition is perfect for indoor shooting ranges that do not allow high powered rifles because of the noise they generate that echoes off of the walls or fear that the bullet will generate so much power that it will pass through or tear up the backstop. It can be fired on smaller plots of land that are safe for firing handguns but where a miss with a rifle bullet would likely travel beyond the property, or the use of a full powered rifle load would disturb nearby neighbours. It is a perfect round for ranchers to dispatch varmints and predators such as coyotes or bobcats that prey on young calves and small livestock, with a reduced chance of scaring larger animals into a stampede. Atomic's 300 Blackout Subsonic is quickly growing in popularity with military and law enforcement tactical professionals as well as civilians in over 35 states to use with suppressed firearms because the bullet does not reach or exceed the speed of sound and does not create a loud sonic boom as it travels. This relatively innocuous cartridge, with its low recoil and report compared to full powered 7.62 and 30-06 loads will serve many shooters, new or experienced, young and old with an alternative target and varmint round to the loud, harsher kicking standard 30 caliber cartridges and this match grade Subsonic has an MSRP on par with standard 300 Blackout ammunition, not the higher price commonly associated with our competitors inferior 300 Blackout ammo.
