I was leaving work last night, going to test fire 80 gr Corbon DPX and 90 gr Hornaday Critical defense ammo I had ordered online when I saw a box of old magazines and catalogs. I filled a small box with the magazines and headed out. I realize this is incredibly unscientific and a box full of catalogs in no way replicates a bad guy, but it was fun. At best this tells something about how the ammo performs relative to the other ammo I tested. I fired two rounds of each, as well as two rounds of WWB 95 gr fmj rounds. I was able to recover all of the bullets, with each pair right next to it's mate. Hornadays penetrated the least, stopping about 2.5 inches in. One round had good expansion, and the other did not. The second round entered almost in the same hole as the first, so I wonder if that resulted in the lack of expansion. the DPX rounds penetrated much farther (comparatively) to about 4.5 inches, with excellent expansion with both rounds. As expected, the WWB FMJ's penetrated farthest, to about 5.5 inches. What surprised me was the marked difference in the Corbons and the Hornadays. Before this, I was biased towards the Hornaday Critical Defense, but as of last night my P3 is loaded with 80 gr corbon DPX. I will try to take some pics of the recovered bullets and post them as soon as I can. Also, I had an FTE with the final round in the magazine (WWB). Then I loaded a magazine full of WWB, and again had an FTE on the last round. Since it was cold and I was hungry I stopped. Anyone else experienced this?
