Chet I agree with you on the first part but not on the second. While the 52 might be a great gun, I just can't see that caliber ever being highly marketable. I thought, (but I may be wrong), that it was one of the things that brought them down.
I think the Ultimate Slam in 50 caliber will be their flagship rifle, but I honestly don't know what it has over the disc elite. A Lehigh conversion on the disc elite is a much less expensive alternative to what that Ultimate Slam is bound to cost. Of course everyone is not a cheapskate like me.
Like you say time will tell. It will be interesting to see what transpires.
