I have no direct experience, but every H&R rifle I've owned or fired has been both reliable and accurate; for the money, I don't really think they can be beat
I like lever actions too, and have played with quite a few in my time. That said, my only centerfire was a Browning BLR, which is quite a piece but not available in pistol chamberings
Marlin has always made a solid, reliable gun, although I've yet to find one with what I would call a 'smooth, slick action' at least as they come from the factory. The Rossi/Puma rifles I've handled have had smoother, lighter actions than comparable Marlins, and are in nearly the same league as the smooth, beautiful (but costly and hefty) Henry Big Boy. I think the fit and finish of the Rossi guns is inferior to that of the Marlin and Henry rifles, but not vastly so; since they are less expensive, and yet seem to have an excellent reputation for reliability and accuracy, this may not be particularly major factor.
Speaking of .357 rifles, my father has always been a big fan of that cartridge, and owns an older Italian lever action (modeled after the Winchester 1873) set up with a peep sight. It has no model markings and I don't recall the importer's name, but it is a smoother functioning, accurate rifle; it has trouble with Hornady's LeverEvolution loadings, as they both chamber and eject very stiffly - I'm not really sure why this, though it may be due to the gun's old-school, lifter-type action
The .357 performs well out of this rifle, with good accuracy and little recoil; .38 Specials have to be single loaded to function properly. I think the Italian replica rifles are some of the slickest, best made leverguns made, and are perhaps the nicest production guns available in pistol chamberings
They are quite expensive, and I can understand how that would turn many people off to them.
Out to a hundred paces or so, the .357 Magnum is quite a capable round, and should do a number on numerous four (and certainly two) legged critters
Versatility has always been one of its strong points, and one can expect good things out of a well-made rifle shooting modern loads
Any of the guns mentioned should work fine if loaded properly, and all have their followers and detractors. If you can deal with the single shot, I think the H&R is a great buy; if you like the levers, Rossi is probably the best value (I think the Taurus/Rossi umbrella is going to be importing the guns themselves now, since Legacy Sports Int. has transferred the "Puma" name to a line of previously mentioned Italian guns). Henry makes what might be the nicest American made piece that I have seen
Like I tell people, find what you like, and buy it; if you find you don't really care for it, buy something else; better yet, buy a bunch, as one can never have too many 'fun guns' IMO
Kind Regards,
