Brief History of .300 Blackout and .45 ACP
First, a quick background on each of these iconic American cartridges:
.300 Blackout
- Developed in 2011 for the military/law enforcement market.
- The goal was to match 7.62×39 ballistics in an AR-15 platform.
- Uses a straight-walled .30 cal bullet in a shortened 5.56mm case.
- Gained huge popularity in AR rifles for suppressed use.
.45 ACP
- Developed in 1904 by John Browning.
- Original load for his Colt M1911 pistol design.
- Large diameter, subsonic 230-grain bullet.
- Remains one of the most popular handgun rounds today.
- Often used in PCC carbines.
Now let’s see how they stack up head to head.
.300 Blackout vs .45 ACP Ballistics
Though designed for rifles and handguns respectively, these two cartridges have some remarkably similar ballistic profiles:
As you can see, subsonic .300 Blackout loads closely match .45 ACP ballistics. The .300 BLK delivers around 50% more energy, but at lower velocities conducive to suppressed fire. Both are sub-1,100 fps to avoid sonic cracks.
When .300 BLK is loaded hot and supersonic, it far surpasses any .45 ACP capabilities. But it also generates more noise and concussion unsuppressed.
Overall, .300 BLK offers a much wider performance envelope tailored to specific needs.
Recoil Comparison: .300 Blackout vs .45 ACP
Despite the rifle vs handgun formats, perceived recoil is not drastically different between equivalent loads:
- In an AR-15 platform, .300 Blackout has very mild, almost 5.56 NATO-like recoil due to the rifle weight dispersing energy.
- From a full-size steel frame pistol like 1911, .45 ACP recoil has a firm rearward push but is still very controllable.
Shooters describe both as having noticeable but not sharp recoil. Muzzle rise is minimal, allowing faster re-acquisition between shots. The .300 BLK rifle format helps make its recoil more easily managed overall.

Effective Range Comparison
The maximum effective range – where shots can consistently strike targets – differs notably between the rounds:
- .300 Blackout – 200-300 yards for subs, 500+ yards for supersonic loads.
- .45 ACP – 50-100 yards, limited by the low pistol velocities.
The high velocity .300 BLK supersonic loads reach out much further than even hot .45 ACP +P can manage. This makes the .300 Blackout extremely versatile for any range scenario.
Suppressor Suitability: .300 BLK vs .45 ACP
One area where the .300 Blackout and .45 ACP shine is suitability for suppression. Their heavy subsonic loads were designed with silencing in mind. Here’s how they compare:
- With subsonic .300 BLK, the combination of low velocity, heavy bullets, and rifle stabilization results in extremely quiet, effective suppression with no sonic crack. Minimal gas blowback.
- Subsonic 230 grain .45 ACP is also nicely suppressed, indeed it was a major factor driving the round’s original development. Pistol configurations allow smaller suppressor sizes.
- Fully-suppressed, subsonic .45 ACP operates in the 110-120 dB range, while.300 BLK subs are ~130-140 dB based on barrel length. Both are very hearing-safe.
Due to the highly controlled gas operation of AR rifles, .300 BLK has an edge for minimal mechanical noise and gas ejection when suppressed. But both work extremely well in tandem with cans.

Terminal Ballistics Comparison
How do the bullets perform upon impacting a target? Here are some key characteristics:
- .300 Blackout – Excellent terminal performance even at subsonic speeds. Tends to create a straight wound channel and deep penetration due to the Spitzer bullet shape. Dumps kinetic energy quickly.
- .45 ACP – This creates a wider permanent cavity due to the large .45 caliber frontal area. Subsonic 230-grain bullets can lack penetration based on load. Mushrooming varies.
- Supersonic .300 BLK offers vastly higher velocities and energy transfer compared to any .45 ACP load. It penetrates deeply through tough barriers.
Overall, the .300 BLK delivers stellar terminal effects for a pistol caliber round, with penetration exceeding what most .45 ACP loads can achieve.
Hunting and Range Comparison
How do .300 BLK and .45 ACP compare for hunting medium game or range shooting?
- At hunting distances under 150 yards, subsonic .300 BLK can humanely take deer-sized animals with proper shot placement using expanding bullets. A lower velocity of .45 ACP is not a good hunting round.
- In defensive shooting scenarios under 100 yards, both deliver adequate stopping power. The .300 BLK has more velocity and penetration, while.45 ACP offers a bigger frontal diameter.
- For plinking and target shooting, supersonic .300 BLK loads extend effective range far beyond .45 ACP. Both are accurate when firing from rested positions.
With the right loads, the .300 Blackout is more versatile as a single solution for hunting, defense, and range recreational shooting at varied distances.
Availability and Cost Comparison
In terms of ammunition availability and cost, there are some significant differences:
- .300 Blackout ammunition has become widely available from all major brands in the past decade. However, expect to pay $1.00+ per round for quality loads. Handloading can save money.
- .45 ACP is enormously popular, produced by nearly all ammunition companies. Bulk target rounds can readily be found for around $0.50 per shot.
.45 ACP still maintains a substantial cost advantage over .300 BLK, with plentiful cheap target ammo and hollow points available. The specialty .300 BLK market commands a premium price point currently.
Weapon Compatibility Comparison
Another major point of distinction is firearm compatibility:
- The .300 Blackout was specifically designed from inception to work in standard AR-15s with only a simple barrel change needed. It is also available in bolt guns.
- .45 ACP requires a firearm specifically chambered in the round. Popular choices include 1911 pistols, submachine guns, and .45 ACP chambered PCCs.
If you already own an AR-15, converting to .300 BLK is a very simple and cost-effective way to change its performance envelope. The .45 ACP requires a dedicated handgun or carbine.
Similarities Between .300 BLK and .45 ACP
Despite coming from rifle and handgun origins, these two rounds share some common traits:
- Heavy, straight-walled bullets are suitable for suppression.
- Can be loaded to both subsonic and supersonic velocities.
- Large .30 to .45 caliber bullet diameters.
- Slower velocity than smaller caliber carbine rounds.
- Require short barrel lengths to maximize subsonic potential.
- Mild perceived recoil in modern firearm platforms.
Their flexible ballistic profiles supporting both suppressed subsonic and powerful supersonic loadings are a key shared advantage.
Key Differences Between the Rounds
Here are the major areas where.300 BLK and .45 ACP diverge:
- The .300 BLK has much longer effective ranges when loaded supersonic.
- .300 BLK has higher velocity and energy potential than .45 ACP.
- .45 ACP diameter creates a wider permanent cavity.
- .45 ACP ammunition remains significantly cheaper.
