I'm going to guess there's not a nickels worth of difference between them. As old/aging as the Black Talons are, they'll still function flawlessly, just as they did when they first came out. I've still got a few boxes in my debris piles.
My suggestion to you would be to save them. Yes, they've got nostalgia value these days. If you can get more Gold Dots, do so. The Black Talons are still a mainstay at gun shows, selling for right about $2 a round/$40 a box.
The only reason production stopped was the anti-gunners declared them evil and then got with their cohorts in the press to name them "cop killers", regardless of no evidence of any cop even being shot with them, much less killed. And the coating was somehow morphed into a coating that would slip right through any body armor. Magic bullets.
I found and bought a partial box of .357s last month. I have a full box, but I figured more is better.
Its good ammo, don't waste it. Don't waste your Gold Dots, either.
