.30-30 Winchester vs .300 AAC Blackout Ammo Comparison - Ballistics Info & Chart
- Caliber Ballistics Comparison
- 07 Dec, 2018
The following ammunition cartridge ballistics information and chart can be used to approximately compare .30-30 Winchester vs .300 AAC Blackout ammo rounds. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer, bullet weight, or jacketing type. As such, the following is for comparative information purposes only and should not be used to make precise predictions of the trajectory, performance, or true ballistics of any particular .30-30 Winchester or .300 AAC Blackout rounds for hunting, target shooting, plinking, or any other usage. The decision for which round is better for a given application should be made with complete information, and this article simply serves as a comparative guide, not the final say.
For more detailed ballistics information please refer to the exact round in question or contact the manufacturer for the pertinent information. True .30-30 Winchester and .300 AAC Blackout ballistics information can vary widely from the displayed information, and it is important to understand that the particular characteristics of a given round can make a substantive difference in its true performance.
| Caliber | Type | Velocity (fps) |
Energy (ft-lb) |
|---|---|---|---|
| .30-30 Winchester | Rifle | 2370 | 1890 |
| .300 AAC Blackout | Rifle | 2250 | 1350 |
Velocity
As illustrated in the chart, .30-30 Winchester rounds - on average - achieve a velocity of about 2370 feet per second (fps) while .300 AAC Blackout rounds travel at a velocity of 2250 fps. To put this into perspective, a Boeing 737 commercial airliner travels at a cruising speed of 600 mph, or 880 fps. That is to say, .30-30 Winchester bullets travel 2.7 times the speed of a 737 airplane at cruising speed, while .300 AAC Blackout bullets travel 2.6 times that same speed.
Various calibers
Energy
Furthermore, the muzzle energy of a .30-30 Winchester round averages out to 1890 ft-lb, while a .300 AAC Blackout round averages out to about 1350 ft-lb. One way to think about this is as such: a foot-pound is a unit of energy equal to the amount of energy required to raise a weight of one pound a distance of one foot. So a .30-30 Winchester round exits the barrel with kinetic energy equal to the energy required for linear vertical displacement of 1890 pounds through a one foot distance, while a .300 AAC Blackout round exiting the barrel has energy equal to the amount required to displace 1350 pounds over the same one foot distance. As a rule of thumb, when it comes to hunting, muzzle energy is what many hunters look at when deciding on what caliber of firearm / ammunition to select. Generally speaking, the higher the muzzle energy, the higher the stopping power.
Again, the above is for comparative information purposes only, and you should consult the exact ballistics for the particular .30-30 Winchester or .300 AAC Blackout cartridge you're looking at purchasing.

Without stating the bullet weights being compared, this writing is worse than useless.
Might wanna also read the barrel length used for testing both. 30-30 velocities tend to be 22-24" barrels vs the 16 of the blackout.
~Absolute “MUST” have the same bullet weight “and’ exact same barrel length is preferred (or no more than within about 2”) for all three: 300 Blackout, 7.62×39, 30-30 (Winchester model 94 Trapper model with its 16" inch barrel). This is the “ONLY” way to “COMPARE” all three of them.
~Also included case capacity volume on all three.
All commercial loads will meet SAMMI specifications and are are tested out of 24" Lija barrels (@ maximum safe chamber pressures). That is where these statistics come from.
They have to be using different weight bullets. The 30-30 velocity is only 5.3% faster, but has 14% more energy. This is physically impossible if the bullets were the same weight.
