Anyone give these a whirl yet?

I was looking at them for a 454 Casull - 260 grain bullet at 1800+ fps at the muzzle.

If the accuracy is even close to that described in this article, looks like a great new hunting load:

Should work well on thin-skinned game like deer, but I'm not a real fan of expanding bullets in big-bore revolvers. That said, I have heard some good things about that load.

Must have been named by someone that use to work for Herter's.

I have not tried this load, but had jacket core separation on a Freedom Arms 260 grain bullet; and those are not supposed to do that. You are better off with a cast bullet on the big bore revolvers when hunting larger/ dangerous game.
