Indeeed they are!
The Super Blackhawk has been my favored sixgun since about 1972. I currently own five, two of which are pre-1973 Old Models. Also three .45 Blackhawks set up like Super Blackhawks.
In my experience, the .44 Magnum is one of the most versatile rounds around, and the Super Blackhawk THE BEST package for the round.
With my handloads, it is flat shooting out beyond 200 yards, and retains enough velocity to be effective at this range. You can shoot it all day without tiring, and its package is small enough to really be carried in a holster and jerked out for quick in-your-face type of shots.
It can take any game found on this continent, at reasonable ranges, and is probably one of the most inherently accurate rounds I've ever used.
And, unlike the bigger five shot custom jobs, recoil is mild enough to allow quick follow up shots, if needed. The .45 Colt, in a Ruger, will shoot through a buffalo, but the .44 Magnum remains one of the best all-round cartridges available today.
