(from Dec 2013)
This is a follow-up to a prior test. In this video I explore one of the self-defense rounds made for .45 Colt, the Speer Gold Dot 250-grain GDHP, part #23984, but I am specifically producing this video to test these Gold Dots from the shorter barrel of the Judge Public Defender.
Gold Dots in .45 Colt are rated on their website at 750 feet per second, from a 5.5" barrel. In my testing from the Public Defender, they were much slower, clocking in at an average of 631 feet per second despite from the short 2" barrel and 2.5" cylinder of the Public Defender.
Note: I'm not making any claims for these videos other than that these are the results I achieved, in my own testing, from the stated pistol(s). I have no intention to make a blanket endorsement or indictment of any product, only to review and report what I found in a given instance. Obviously it is incumbent upon each individual to conduct their own research and make up their own mind about which defensive ammunition is best for their own purposes, in their own firearms.
The standards I use to judge bullet performance are the standards established at the 1987 and 1993 Wound Ballistics Conferences, and subsequently adopted by the FBI.
