The current .300 Blackout price per round typically ranges from $0.60 for entry-level steel-cased FMJ to over $3.50 for premium subsonic expanding ammunition.
As of mid-2026, standard brass-cased supersonic range ammunition averages between $0.70 and $1.00 per round depending on the brand and box quantity.
Subsonic ammunition commands a higher premium, consistently costing between $0.84 for bulk OTM loads and $1.60 or more for specialized polymer-tipped defense rounds.
For example, AAC 125-grain FMJ can be found for $0.68 per round, while Hornady Black 110-grain V-Max costs roughly $1.67 per round.
Prices vary significantly based on whether you are purchasing lightweight supersonic hunting loads, heavy 220-grain subsonic rounds, or bulk FMJ for the range.
Compared to 5.56 NATO or 7.62×39, .300 Blackout remains a more expensive cartridge, though budget-friendly bulk options continue to improve market accessibility.
300 Blackout Price Per Round
| 300 Blackout Load | Bullet Weight | Ammo Type | Box Size | Box Price | Price Per Round |

Understanding the 300 Blackout Price Table
The table above reflects live retail pricing for some of the most popular .300 AAC Blackout loads available. When analyzing the current 300 Blackout ammo cost, several trends emerge:
- Typical price per round: The median cost for reliable, brass-cased range ammunition sits comfortably between $0.70 and $1.00 per round.
- Cheapest current option found:Currently, the most affordable high-quality brass option is the AAC 125-grain FMJ at $0.68 per round. Alternatively, steel-cased Wolf 145-grain FMJ can be found closer to $0.60 per round when buying in bulk.
- Most expensive option found:Premium specialized boutique loads, such as the Lehigh Defense Maximum Expansion 194-grain solid copper hollow point, retail for an astonishing $3.50 per round.
- Typical supersonic cost: Standard supersonic FMJ rounds typically cost between $0.68 and $1.00.
- Typical subsonic cost: Subsonic prices start slightly higher, around $0.84 per round for bulk options, quickly scaling to $1.60+ for reliable defensive rounds.
- Why prices differ between loads: Cost variance stems directly from bullet weight and construction. A 220-grain subsonic projectile uses almost double the raw material of a 110-grain bullet, which inherently raises the production cost.
How Much Does 300 Blackout Cost Per Round?
Figuring out exactly how much you will pay depends heavily on what you intend to do with the rifle. The 300 Blackout ammo price per round scales aggressively as you move from range plinking to specialized tactical applications.
To calculate the exact price you are paying, always use this formula:
Price per round = box price ÷ number of rounds
For instance, a $33.99 box of 50 rounds yields a cost of roughly $0.68 per round, whereas a $33.49 box of 20 rounds calculates to $1.67 per round.
300 Blackout Price Per Round By Load
Bullet weight dictates the trajectory, terminal ballistics, and cost of the cartridge. Here is a breakdown of the 300 Blackout price per round by load based on current listings:
- 110 Grain:Typically premium supersonic hunting or defense loads (e.g., Barnes VOR-TX at $2.25/round or Hornady V-Max at $1.67/round).
- 115 Grain to 125 Grain: The sweet spot for supersonic range ammo. Prices range from $0.68 (AAC FMJ) to $1.00 (Sig Sauer FMJ).
- 145 Grain to 150 Grain:Common for cheap steel-cased plinking (Wolf 145gr at ~$0.60/round) or standard brass (Veteran Ammo 150gr at $0.70/round).
- 190 Grain: Often utilized for mid-weight subsonic expansion, like the Hornady Sub-X, costing around $1.60 per round.
- 200 Grain: A very popular subsonic weight. Winchester Super Suppressed 200-grain Open Tip runs about $1.05 per round.
- 208 Grain to 220 Grain: The classic heavy subsonic loads. Bulk AAC 220-grain OTM can be found for $0.84/round, while premium Barnes 220-grain OTM sits closer to $1.40/round.
300 Blackout Supersonic Price Per Round vs Subsonic
The defining feature of the .300 AAC Blackout is its ability to seamlessly transition between supersonic and subsonic loads without modifying the host firearm. However, this versatility comes with a price difference.
| Load Type | Typical Price Per Round | Example Load | Why Price Differs |
| Supersonic | $0.68 – $2.25 | AAC 125 gr FMJ | Uses lighter bullets (110gr – 150gr) requiring less raw material (copper/lead). Standard manufacturing processes keep costs lower. |
| Subsonic | $0.84 – $3.50 | Hornady 190 gr Sub-X | Requires heavy projectiles (190gr – 220gr) using more raw material. Demands specialized powder charges to guarantee cycling while remaining below the speed of sound. |
Subsonic 300 Blackout subsonic price per round is almost universally higher because of the massive bullets required to cycle the AR-15 action reliably with reduced powder charges.
300 Blackout FMJ Price Per Round
If you are just heading to the range, Full Metal Jacket (FMJ) is your best friend. The current 300 Blackout FMJ price hovers between $0.60 (for steel cases) and $0.75 (for brass). Purchasing bulk 250-round or 500-round cases from manufacturers like AAC or Palmetto State Armory brings the cost down significantly.
300 Blackout Hunting Ammo Price Per Round
Because the cartridge is highly effective on hogs and whitetail deer at moderate ranges, the 300 Blackout hunting ammo price is a common concern. Expect to pay between $1.60 and $2.50 per round. Loads utilizing monolithic copper hollow points, like the Barnes 110-grain TAC-TX ($2.25/rd), dominate the hunting space but command a premium due to complex bullet manufacturing.
300 Blackout Premium Ammo Price Per Round
Premium defensive ammunition, featuring bonded soft points or specialized polymer-tipped expanding subsonic projectiles, represents the top of the market. The Hornady 190-grain Sub-X ($1.60/rd) and Federal Fusion MSR ($1.82/rd) are standard benchmarks. You are paying for terminal reliability, flash-suppressed powders, and nickel-plated brass.
300 Blackout Price Per Round By Box Size
Retailers consistently incentivize bulk purchases. Buying a standard 20-round box of range ammo might cost you $1.00 per round, whereas buying a 250-round bulk pack of the exact same ammunition drops the price to $0.75–$0.84 per round.
300 Blackout vs 5.56 Price Per Round
| Cartridge | Example Load | Box Size | Box Price | Price Per Round |
| .300 Blackout | AAC 125gr FMJ | 50 | $33.99 | $0.68 |
| 5.56 NATO | Igman 55gr M193 FMJ | 1000 | $440.00 | $0.44 |
| .223 Remington | Wolf Polyformance 55gr FMJ | 20 | $8.79 | $0.44 |
| 7.62x39mm | Wolf Performance 123gr FMJ | 1000 | $490.00 | $0.49 |
(Prices based on current 2026 data. Bulk case pricing used for military calibers where applicable.)
When comparing 300 Blackout vs 5.56 price per round, 5.56 NATO is unquestionably cheaper. Standard 5.56 NATO can easily be sourced for $0.44 per round, making it roughly 35% to 40% cheaper to shoot than the most affordable .300 Blackout brass.
300 Blackout vs 7.62×39 Price Per Round
Similarly, when looking at 300 Blackout vs 7.62×39 price per round, the traditional Soviet cartridge wins on budget. Steel-cased 7.62x39mm averages $0.49 per round. However, .300 Blackout offers vastly superior suppressor performance and uses standard AR-15 magazines and bolts, which offsets the ammunition cost for many shooters.
What Affects 300 Blackout Price Per Round?
Several factors directly manipulate the 300 Blackout ammunition cost:
- Bullet Weight and Construction: Heavier bullets and monolithic copper designs cost more to produce.
- Supersonic vs Subsonic: Subsonic rounds generally cost 15% to 25% more than their supersonic counterparts.
- Intended Use: Range FMJ is cheap; terminal defensive and hunting ammunition requires stringent quality control.
- Box Quantity: Buying in 250-round or 500-round lots drastically reduces the cost per trigger pull.
- Market Demand and Availability: While .300 BLK is widely available in 2026, raw material constraints (like copper pricing) continue to set a firm price floor.
