(from May 2014)
Eighteenth 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 Winchester White Box 115-grain jacketed hollow point bullets in stamdard pressure. This is part #USA9JHP.
This ammo was generously supplied by one of my viewers, so thanks for that!
I am chronographing the rounds as well as firing five 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, the ammo performed really very well indeed! The penetration was absolutely excellent. The expansion was not great; they did all expand, but not with the clean consistency and precision we're used to seeing from such as the HST or CorBon DPX rounds, and there were some issues with shedding of weight (in the form of petals that dropped off).
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.
