I picked up a Glock 21SF from a Gunsmith a few weeks ago and he told me at the time I shouid strongly consider using Corbon DPX for defense. He stated that it's documented kill percentage in hunting is the highest. I should have asked him where he found this documentation. However, I am researching this....slowly..I have a lot of 230gr JHP on hand....
I spoke to a friend who does much rifle shooting and hunting about Corbon. He said that it tends to over penetrate and copper fouling it excessive.
Well, I have an LCP on order and I'd be looking for as much penetration as this small round can provide. Perhaps the Corbon would have an edge. It's expansion seems to be excelent also. I doubt copper fouling would be excessive at pistol velocities.
