The article was more about trying to find a totally new wildcat that had never been done before.
It would be a useful round along the lines of the ever popular 358 winchester or 375 Scovill.
I think wildcat's are cool, sort of, I toyed with the idea of building a 6.5 RSAUM and converting my Mountain Rifle 260, but then all the things I really like about the 260 would be gone so I would have to buy another and the 6.5 RSAUM's performance would be awfully close to that of a 270 win.
I decided I could afford to own more nice guns without spending the $ on a custom.
