In this video we take a look at the terminal ballistic difference between full metal jacket and soft point ammunition. We tested the ammunition using a DelTon Echo 316 AR-15. We fired our rounds from 25 meters into an FBI grade synthetic gelatin that is used for ballistic testing. We purchased our gel from clearballistics.com.

A full metal jacket bullet features a lead core surrounded by a metal jacket. A soft point bullet is similar to a full metal jacket expect the lead is exposed at the tip of the round. The FMJ is designed to tumble inside of soft tissue. This creates a large wound cavity while maintaining the bullets shape and weight. SP rounds fragment upon impact. This creates multiple pieces of the projectile which transfers all of the rounds kinetic energy into the target. The fragmentation of the bullet is also meant to limit the risk of over penetration.

Our results were somewhat surprising. I expected to see a clear difference between the FMJ and SP's performance. Our test showed that our FMJ tumbled into the gelatin and only penetrated to the 15 inch mark. The permanent cavity was roughly 1.5 inches throughout the gelatin. The soft point fragmented as designed. Throughout the gelatin we found pieces of jacket and lead core. The SP was able to transfer more of its energy into the block. This was clearly shown in the permanent cavity left by the SP round. The largest channel was roughly 1.75 inches in diameter. Surprisingly the SP round over penetrated out the 16 inch block.

Over all the rounds performed as designed, but keep in mind this was only one test. I would like to conduct more tests to confirm our findings, however; the cost of these tests makes this impossible.
