I've done some research and I see that the 230gr does not gain a significant amount of velocity out of a 16" barrel over your standard 5" handgun barrel. I found an article that demonstrated where the lighter loads, the 165 gr specifically, gained 200ft/sec out the barrel but fragmented on impact with the ballistics gel and penetrated just over 5". Is 230gr the way to go? Right now, I have PDX1 230gr bonded hollow point but just checking into other loads. Here is the article: http://www.shootingillustrated.com/index.php/6626/pistol-caliber-carbines/ Wanna kill these ads? We can help!
