Atomic Ammunition 300 Blackout Subsonic 220gr HPBT Rifle Rounds - 50 Box / 10 Case
Atomic
The Atomic 00410 3030 subsonic ammunition delivers a straight-shooting option for hunters and shooters who want reduced recoil without sacrificing stopping power. Built around the .30-30 Winchester cartridge, subsonic loads are engineered to stay below the sound barrier—useful for hunting in noise-sensitive environments or when you want a gentler shooting experience without the sharp report of standard rifle rounds. This 50-round bundle gives you 10 boxes of Atomic's subsonic ammunition, making it practical for serious hunters who shoot regularly.
Each round pairs a 165-grain lead round nose flat-point bullet with a subsonic powder charge, a combination that favors accuracy and terminal performance at closer ranges typical of .30-30 hunting. The flat-point design is a classic choice in lever-action communities because it feeds reliably through tube magazines and delivers consistent energy on game. The lead construction and heavier grain weight make these rounds a no-nonsense option for deer and similar-sized game where controlled, predictable impact matters more than extreme velocity.
If you're running a lever-action rifle, a bolt gun, or a semi-auto chambered in .30-30, subsonic ammunition lets you enjoy the cartridge's heritage and inherent short-to-medium-range accuracy without the muzzle blast. This bulk package makes sense for hunters who train year-round or stock up before season—you get consistent ammunition from the same manufacturer and lot, which helps with group consistency at the range or in the field.

Yes. Subsonic .30-30 Winchester ammunition chambers and feeds through standard .30-30 lever-action rifles. The flat-point bullet is designed for reliable feeding in tube magazines, which is standard for many traditional lever guns.
Subsonic ammunition is loaded with a reduced powder charge so the bullet travels below the speed of sound (roughly 1,125 fps depending on altitude and conditions). This produces less muzzle blast and recoil, which some hunters prefer for shooting comfort or in noise-sensitive areas, though at some cost to velocity and effective range compared to standard .30-30 loads.
The Atomic 00410 uses a 165-grain flat-point bullet suited for medium-sized game at short to moderate distances. Terminal performance and reliability depend on shot placement and range, as subsonic velocity is lower than standard .30-30 loads. Confirm it's appropriate for your intended game and hunting situation.
This bundle contains 50 rounds total, packaged in 10 boxes. The exact round count per box is listed in the specifications; confirm your order total before checkout if you need a specific quantity.
