RE: Winchester 94 ranger Lever action...
Personally, I'd only "take one" if someone was Giving it to me...Winchester doesn't know how to make their 94 action cycle pistol cartridges worth a d@mn, and typically their accuracy and quality is a bit less than satisfactory, especially in newer models...in .30-30, the 94 is great, but not in pistol cartridges.
The Marlin leveraction 1894's are much better rifles. Rossi's are also nice, and Ruger's .44mag isn't bad, but ugly, and rather pricey.
Just comparing the two .357mag and .44mag, I'd pick the .44mag. I'm a huge .44mag fan, so I may be biased, but it's a much more capable round. It costs a little more to shoot, if you're just planning to plink with this gun, but for any hunting, the .44mag will serve you better.
$350 is a typical price for a new Ranger 94 pistol cartridge rifle, but you won't convince me to buy one for that much, like I said, you'd almost have to give it to me.
To put in into perspective, I bought a Ranger 94 Compact (typically compacts are more expensive) for $292 in .30-30 a month ago, the same price was on the .357mag version.
