(from Oct 2013)
In this test I examine DoubleTap Ammo's Equalizer, an exotic patent-pending round in .45 ACP +P. It includes two bullets in each cartridge; a 185-grain JHP on top of a 70-grain hardcast bullet (for a total payload of 255 grains, quite heavy for a .45 ACP round). It is rated on the box at 835 feet per second from a 5" barrel, although in my testing, they were notably faster, clocking in at an average of 873 feet per second from the 4.6" barrel Glock 21, and a respectable 794 feet per second from the 3.3" barrel of the Springfield XDS.
I use ClearBallistics.com's synthetic ballistic gelatin to determine penetration and expansion characteristics, and fire multiple rounds to get a more representative picture of what the ammunition is capable of. Testing with just one round might give you an overly pessimistic or overly optimistic view of what the ammunition can do; the more rounds you can test, the more comprehensive of a picture you can get.
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. Also keep in mind that individual firearms can be persnickety; my Glock may feed a particular round consistently whereas your Glock might not work as well with those rounds, so -- please conduct your own testing before trusting any particular ammo.
