Frequently Asked Questions

Which ammunition caliber, 300 Blackout or 5.56x45mm, performed better in barrier testing?

In the "Ultimate Barrier Testing" conducted by Banana Ballistics, 300 Blackout generally outperformed 5.56x45mm. While 5.56 showed an advantage against 3/8-inch steel, 300 Blackout successfully penetrated lumber, sand, and concrete blocks, making it the overall winner of the competition.

What were the key ballistic differences between 300 Blackout and 5.56x45mm in the test?

The 300 Blackout (123 gr FMJ) produced 1340 ft/lbs of muzzle energy and 2215 fps velocity, with a Sectional Density of 0.185. The 5.56x45mm (55 gr FMJ) achieved 1105 ft/lbs of energy and 3008 fps velocity, with an SD of 0.157.

How did 300 Blackout and 5.56x45mm perform against different barrier materials?

300 Blackout penetrated lumber, sand, and concrete, while 5.56x45mm penetrated lumber and steel plates but failed against sand and concrete. This difference in barrier performance determined the competition's outcome.

What is Sectional Density and how does it relate to bullet penetration?

Sectional Density (SD) is a measure of a bullet's penetration capability, calculated by dividing its weight by its diameter squared. A higher SD, like that of the 300 Blackout in this test, generally indicates a greater potential for penetrating various materials.
