My pick hands down is the .44 Magnum. First reason is that it comes, or rather came, in that superbly finished Super Blackhawk, exquisitely gripped with the Dragoon grip frame and 7 1/2" barrel. Its still available, ofcourse, but not quite the same as when introduced.
And the .44 Magnum cartrodge is just so versatile. I've used the Sierra 180 gr. JHC bullet pushed to just over 1700 f.p.s. for some longer range varmint shooting, heavier 240 gr ~ 265 gr. bullets around 1400 f.p.s. and shot a few 320 gr. cast. One of my pet loads was 25.0 grs. DuPont IMR-4227 with the 245 gr. Lyman #429421 SWC. I've shot, plinking, the rams at 200 meters, and even plunked floatin logs in the river at estimated 500~600 yards. (Estimation only~ wild guess as to range) And bullet selection is almost infinite. Powders such as #2400, Winchester #296, H110, H4227 And Winchester 572 and 244 arr work well. Accuracy is alway right on. And being able to use the more timid .44 Special in these guns is also of great convenience. And, my Super Blackhawk with its barrel shortened to 5" makes a very handy six-shooter, actually a five shooter, for general walking around use.
While some claim velocities nearing 2,000 f.p.s. with certain loading data, my chronograph only showed just over 1700 f.p.s. using their data. Maybe they used a solid bsrreled Contender, while I used a revolver.
I once had an 8 3/8" full lug barreled S&W Model 29 that was the next thing to a .30-30 out to about 150 yards or so.
I reckon my penchant for the .44 Magnum came from my reading of Elmer Keith's experiences with the old .44 Specials of his day. I tried to duplicate that with a custom Colt New Service, but just as I was getting into that, along came the new .44 Magnum.
The .44 Magnum is not as new now as it once was, but neither am I. Yep, like the .44 Magnum.

Addendum: Well, the cartridge is of no value without the gun, here is my .44 Battery, two on bottom roght are .44 Specials, but.....
