(from Dec 2014)
Twenty-Seventh in a series of a quest to find the overall best defensive ammunition for modern 9mm pocket pistols (such as the Sig Sauer 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 115-grain +P Buffalo Bore JHP (part #24D). It is rated on the box at 1300 fps; my 5-shot average from the shorter 3"-barrel pistol produced an average of 1203 fps.
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 three bullets into a denim-covered gel block, and saw that all failed to expand and overpenetrated. At that point I decided to finish off the block by firing two more bullets into it without denim (a bare gel test). When fired into bare gel, the ammo performed very well.
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.
