When H&R bought out...............
Vernon O'Brien, it became the "H&R" Ultra Wildcat (as O'Brien coined the name).
Basically, it was a higher-grade stock w/basketweave "checkering" w/some Weatherby-type inlays (a bit farther-out than the SAKO Deluxe) and a custom barrel; a bit garish to some, but I felt the quality of the SAKO action and the overall diminutive rifle (most had 20" barrels, I believe) still made it a class act. H&R had it for a couple years and ran it into the ground, like Colt did w/the modern "Sharps" and then later, Ultra Light Arms.
MANAGERS that think they "know" guns and can capitalize on their buying power, like the Dakota fiasco.
Actually, the Ultra Wildcat used the L461 receiver, and was chambered for the 17 Mach IV; 17 Javelina; 17/222; 17/223; 17/222Mag. and perhaps some of the wildcat cartridge shapes that were in vogue at the time. I've never seen any figures as to how many were made under either ownership. I did see one earlier this year on one of the auction sites. Hope someone w/more knowledge will chime in, I always wanted to know more about the rifle story and about the original developer.
If you found an U/Wildcat in good shape, it would probably be too valuable to use in competition, unless someone had already put a new barrel on it.
