(From Aug 2014)
Twenty-fourth in a series of a quest to find the overall best defensive ammunition for modern 9mm pocket pistols (such as the Sig Saur P938, Taurus PT709, the Ruger LC9, Kahr CM9, Beretta Nano, Kel-Tec PF9 or S&W Shield or any other popular 9mm micro-pistol using a barrel length of approximately 3").
In this installment, I am testing the CorBon DPX solid-copper hollow point bullets.
This ammo was generously donated by CorBon, so thanks for that!
I am chronographing the rounds as well as firing multiple rounds per block so that we get a more statistically relevant result, rather than the typical ammo test where only one round is fired. Ammo can behave a bit unpredictably, and the results of any one bullet are not necessarily representative of how the ammunition performs overall.
In this test, I fired five bullets into a bare gel block, and then five more bullets into a denim-covered gel block. Unfortunately one of the bullets fired in the denim-covered block exited out the side of the block and was lost, so in total I ended up with 9 samples: five in bare gel and four thru denim.
In this test, the ammo performed above my expectations. Eight out of the 9 bullets met or exceeded the minimum penetration target (12"), and the 9th bullet came very close (it ended up at 11.5"). All the bullets expanded properly, they all penetrated well, and overall it's a quite good performance.
The purpose of this testing is to find which rounds of ammo perform well enough from a short 3" barrel that they can reliably deliver the penetration (with expansion) that has been documented and proven necessary in order for the bullet to be able to reach the vital organs of an attacker and deliver an incapacitating hit.
