As 106rr says, Steyr has problems with the feds. Might be associated with a sale to Iran in 2003-4 of 800 firearms for "law enforcement". The Steyr Mannlicher line of wood-stocked hunting rifles were available as special order items from WalMart for a while, ending I think in 2006. (IMO, at $1,600-1,800 not the kind of item one would think would be in high demand by the traditional WM shopper) In any event, Steyr does not seem to have an active importer to the U.S. at this time.
As best I can figure, the Classic, Prohunter, and Forester all use the SBS action introduced in 1996. The Forester seems to be no longer marketed anywhere, but was a subdued version of the Classic. Where the Classic was highly polished blue, the Forester was bead blasted matte. Forester stock was oiled wood with low sheen. Prohunters are stainless bead blasted or some kind of grey coated finish with a composition stock with non-traditional lines. When and if available, Prohunters come in some large chamberings, the 376 Steyr and the "Big Bore" in 450 Marlin.
