Black Talon is a brand of hollow-point pistol and rifle ammunition introduced in 1991 by Winchester, primarily intended for law enforcement and personal defense use.

Black Talon rounds were known for the unique construction of the bullet and its sharp petal shape after expansion following impact with tissue or other wet media.

[3] Though widely misreported to be Teflon, molybdenum disulfide, or wax, the ammo has an unusual black appearance compared to other copper-jacketed or lead bullets.

[6] The rifle version did not share the handgun bullet's barbed petal design and was basically a solid copper hollow-point with a hollowed out rear shank containing a lead core in a steel liner to prevent jacket rupture thus maintaining necessary penetration in tough game.

On internet forums, gun enthusiasts frequently joke that that SXT stands for "Same eXact Thing",[13] though the official branding is “Supreme eXpansion Technology”.

The hollow point cavity dimensions and angles of the meplat were altered to enhance reliability of expansion, though the basic "reverse taper" design pioneered by the Black Talon was retained.

Besides further dimensional changes to the hollow point for reliable expansion, the distinctive perpendicular petals were made longer yet more rounded at the tips to retain stiffness.

The most obvious difference from the SXT is that the bonded design, meant to maintain structural integrity through difficult intermediate barriers like auto-glass, largely prevents the sharp petals from peeling away from the lead core and fully protruding into the wound track.
