For those who aren't familiar with the T-Series, about 10 years or so ago Winchester came out with the Black Talon. So called due to the black coating of the bullet (lubox or lubealloy) designed to reduce friction and heat buildup in the barrel as well at the projectile's very novel expansion qualities. Instead of simply expanding, the bullet "peeled" to create what were known as "talons" which did a very respectable job of acting like a food processor in the wound track.
The bullet worked great. It worked even better in the mind of Congress and the public so Winchester pulled them off the market. Rather than going the way of other "evil" products such as the Lawn Dart, Winchester took the coating off, made the bullet an even more efficient food processor and dubbed it the SXT (Supreme Expansion Technology).
Winchester reintroduced this ammo as the Ranger T-Series and markets it only to LEO and Military. You wont find this at Walley World. Ranger T's have greater performance and stopping power that the original Talons. This is some of the most extensively tested ammo ever developed. Winchester actively tries to keep Rangers only in the hands of LEO/Military and out of the hands of civilian shooters. It's Winchesters rule not a law so its perfectly legal to own and use (state and local lunacy aside).
Remember, you can have the best ammo in the world, pack a .45 or a .22, but it's all for naught if your shot placement is bad. Shot placement is key.
Just my .02¢.
