Back when it was introduced and pretty popular, I tried testing it but had so many reliability issues with it jamming and hanging up I got frustrated and stopped. I sold the remaining 10 boxes I had and that was that. I got more than double what I had paid for it. BTW, I also tried it in a friends 1911 with no better results than in my 1911. I decided right then and there I wanted no part of it. IMHO, it was more hype than anything spectacular.
The Black Talon was nothing special however its black color and case slits did make it look "sinister" and was waged war against by the gun hating media. Winchester stopped production of the "Black Talon", waited a brief period of time and came out with almost the identical loading but called it something else. If I recall correctly, they even changed the color, however it was still a disguised Black Talon. That said, once the reality that the loading was nothing revolutionary, demand waned and I guess the media felt good about torpedoing it - even though it was still available as a different name.
I had read a few test result articles years back and from what I remember, although it may have been a good "concept" for its time, it never paned out to be anything revolutionary. Today there are many modern bullets that are way better than the Black Talon.
