Is that the same as the old "Black talon?"
Time for the old story I suppose.
LE agencies tend to use four types of JHP rounds:
Remington Golden Saber
Speer Gold Dots
Federal HST
Winchester Ranger-T
The Golden Saber, Gold Dots, and HST are available for civilian sale (in those 20-round boxes you see at stores). They are sold to LE for a premium in 50 round boxes. All of these rounds are typically unbonded (with bonded versions available) except for Speer Gold Dots.
In regards to JHP expansion, Federal HST and Winchester Ranger-T (in their unbonded varieties) have the best expansion of any commercial round IMHO.
Although HST and any of these other rounds will suffice, I still like the Ranger-Ts since I know a lot of LE around me use it. Mas Ayoob and others recommend to carry what your local LE agency uses (shouldn't actually be an issue however). Unfortunately, Winchester doesn't sell Ranger-Ts in stores, its for LE only. This isn't a legal thing, its Winchester policy.
In 2000, Winchester stopped sales of the "Black Talon" for both civilians and LE. They made some updates to the bullet design and sold it as the Ranger SXT. Winchester's Ranger line is sold to LE only. The bullet was updated once again in 2007 and became the "Ranger-T" (still not for public sale).
Winchester's current premiere self-defense round for civilians is PDX1. PDX1 is a good round but it is bonded and doesn't provide the expansion which the unbonded Ranger-T does. Ranger Bonded is actually the exact same thing as PDX1.
