I was looking into this as well..Don't know anyone who has one though..Whats interesting is all the docs on this only mention the .58 in passing, guess the .50 and .54 we more mainstream..Looks to be the early version of the Black Diamond,,with nice wood stocks..1:38 twist so its between a Hawken and the newer rifles..
Price seems about right for those I've see listed..especially if its never been fired, NIB..But thats an opinion, I recently saw a brand new BD XR for 319.
