AllenR brought up a valid point when he mentioned the Underwood technology rounds versus other various self defense rounds. For the last day or so I have been reading and watching YouTube on the Underwood round. The ogive is copper and varigated with the defense round not having the penetration rate that a round nose would have. I am referring mostly to .45ACP. It's hard to imagine a 120 grain bullet that can cause that much damage with a smaller grain bullet than a 220grain Hornady Critical Defense round would have. I have seen where Ruger has come up with another round very similar to the Underwood but no real ballistic tests that you can draw a good conclusion with. Underwood has only 1 viewing on YouTube on the defensive round and the penetration round. I am wondering if anyone else has tried any of the new rounds and what conclusions have you drawn? I seem to be a little skeptical about the smaller grain bullet however as he stated technology has come a long ways in the last couple of years. Has anyone tried it and if so, what conclusions did you draw? They are an expensive round-about $35.00 for a box of 20 but you can't put a price on human life. I don't mind spending the money for SD, IF the round is as good as they profess. Anyway, at least it's food for thought.
