Description
- These are the four core fundamentals on which Atomic Ammunition has built its business. In the past few years, Atomic Ammunition has conducted an extensive due diligence process to create unique loadings for rifles and self-defense pistols. They used three of the most well-known independent test labs within the United States to reconfirm their findings and the security of each load. Atomic Tactical Cycling Subsonic ammunition is packed with heavy caliber bullets. The heavier bullets provide the best ballistic power and performance on the target while staying under the noise barrier. This helps eliminate the sound cracks common with ammunition of this caliber. This makes these rounds ideal for use with suppressors. For the best results, you should use at least 100 yards and rifles with a 1-in-9″ or greater twist rate. This ammunition is brand-new production, non-corrosive, and is in boxer-primed brass cases that ammo can reload.
- Sierra MatchKing bullets are made with very thin jackets held to precise tolerances for the diameter and weight. They are Hollow Point Boat Tail bullets that feature a small meplat, which gives them a higher ballistic coefficient. The accuracy of these bullets has been widely praised worldwide and has been utilized to win more competitions for target shooting than all other target bullets from other manufacturers.

Remy Vance –
This is the quietest 7.62×39 ammunition I have ever used in my suppressed AK. The 220grn bullets cycle my rifle flawlessly without any adjustments. The consistency from round to round is impressive. Atomic Tactical has a customer for life.
Peter Anderson –
Living on a larger property, I need to manage pests without disturbing the neighbors. This ammo is the perfect solution. The subsonic report is a gentle ‘thud,’ and the heavy grain bullet has fantastic terminal performance on raccoons and coyotes. Highly effective and discreet
Scarlet Jacobs –
Every round is pristine. The brass is clean, the primers are perfectly seated, and the projectile is uniform. This is clearly ammunition made by shooters, for shooters. The attention to detail in the manufacturing process gives me complete confidence in every shot
Julian Frasier –
Not only is the ammo excellent, but the service was too. I ordered on a Tuesday and it was on my doorstep by Friday. The ammo was packed securely in a discreet box with no chance of damage. A+ experience from start to finish.

I’ve tried every subsonic 7.62×39 load out there, and this is the one that finally gets it 100% right. It cycles my short-barreled, suppressed rifle without a single hiccup. The Atomic Tactical Cycling ammo lives up to its name perfectly.
Daren potter –
I was shooting groups at 50 yards and was amazed at the consistency. The point of impact is predictable, and the low velocity doesn’t seem to hurt accuracy at all for my intended uses. This is high-quality, precision subsonic ammunition.”
Shawn Bradley –
This ammo allows me to get valuable trigger time in my AK platform without the concussive blast and noise. It’s much more pleasant for extended training sessions and is fantastic for introducing new shooters to the platform. Worth every penny.
Nathan Boyle –
The 220grn bullet is a thumper. You can feel the energy transfer on steel targets. It’s incredibly satisfying to shoot. The cycling is smooth and reliable, which isn’t always the case with heavier subsonic loads. Atomic Tactical nailed the formula
Jimmy Conrad –
I’ve had problems with other subsonic brands failing to cycle the action, turning my semi-auto into a single-shot. This ‘Cycling’ ammunition is aptly named—it runs my rifle like a dream. Finally, a product that delivers what it promises.
Terry Wells –
I had a question about the optimal barrel twist rate for this ammo before ordering. I used the website’s chat feature and got a clear, knowledgeable answer within minutes. It’s refreshing to deal with a company that knows its products and cares about its customers
