I have a Ruger 77/357, and a couple of pistol caliber lever guns, just not in .357.
Normally, if we were talking rifle caliber guns, Id take the bolt gun over the lever without hesitation. But in this case, the lever makes more sense, as you get twice the ammo in the gun, and its easier to work compared to the Ruger.
The Ruger seems to be an OK rifle, but it has its issues, especially if youre planning on using it for anything serious.
My only real complaints with it are, the bolt knob is small, and if you use a scope, the handle could be shaped better to give more clearance. Its not the fastest or easiest bolt gun to work.
If you use .38's, expect to get stoppages due to rim lock. Once you get one, you have to stop, remove the mag, and fiddle with the rounds to get them unbound. I havent had any troubles with the .357's, and they seem to work fine.
The mags only hold 5 rounds, arent real easy or natural to change, and I find them somewhat fiddly. The rounds tend to rattle a lot too. They also arent cheap if you want spares.
Mine seems to like 125 grain JHP's the best, and doesnt like 158 grain LSWC's at all.
