And you can get it in 9mm Mak and many others. According to the websites Hornady critical defense numbers 9mm 115gr. 1140/332 (vel/energy at muzzle) vs. the Pow'R ball 9mm (p+) 100gr. 1450/467 (vel/energy at muzzle).
Any thoughts ?
From the very limited and generally informal test results I've seen, the soft hollowpoint filler in the Critical Defense ammo and in Federal's Expanding Full Metal Jacket offering seems to offer an increase in expansion reliability over many other rounds.
My understanding of the purpose of the Pow'r Ball's plastic tip is feeding reliability, not prevention of plugging by barrier material. Also, in the Pow'r Ball tests I've seen, the bullet and jacket often come out in pieces, where the Critical Defense rounds appear to retain virtually all of their weight .
I haven't seen a head to head test of the new Hornady and Federal rounds against the CorBon Pow'r Ball, but it sure would make an interesting comparison.
Anybody know a gun writer with access to lots of free ammo from all 3 companies?
They actually do promote it as a solution to plugging. From the website:
Pow'RBall will not get plugged by heavy clothing. This ammunition will give you confidence and peace of mind knowing you can count on it in a critical situation.
As far as performance is concerned, I've seen the same kind of results from tests I've read - jacket separates a lot. IMO, Cor-bon is a little too proud of that round. This niche bullet is simply a HP plugged with a little piece of plastic. It doesn't appear that they're even bonded bullets. So they've got a low-quality, low mass (only 70grn in .380, 100grn in 9mm), high-velocity JHP with a bit of plastic in the end of it.
Considering that the Hornady ammo is of better quality manufacture, a more effective bullet mass(90grn in .380, 115/124/147grn in 9mm), and 40 cents/round cheaper than the Pow'rball, I'll stick with the Hornady.
