Tony,
I had a lone eagle in .300 Win. Mag. which I regret trading in as it was more accurate out of the box than any of my factory TCs. I heard awhile back that they quit making them due to lack of demand although there are still quite a few good ones available on the used market, at least here in Minnesota. Their 45/70 BFR is the most accurate out of the box factory revolver I've owned so hopefully they'll keep making that for a few years as I'd like a .475 Linebaugh short cylinder model too!
