I like the idea but I doubt that it will last very long. The .357 magnum is a fine handgun round and does quite well in a lever action rifle but I don't see a need for a bolt action in this chambering.
Now if Ruger wanted to sell a lot of rifles they should bring back the semi automatic .44 magnum carbine and also offer it in the .357 magnum. I would break down the door to get my hands on one of those rifles again.
I have always found these bolt action pistol cartridge rifles interesting but the price would have to be really good before I would ever pick one up. The Ruger has a little more appeal for me but as said the prices they go for is pretty high now. If I remember right I think Remington made a bolt action 44 a long time ago as well.
My Marlin lever action 44 has served me well for a bit more than 25 years now so that is probably the only one I will ever have or need.
Remington did indeed make a .44 mag bolt gun, the M788, a very inexpensive bolt rifle from a couple decades ago. And, as a matter of fact, Ruger did already bring back their semi-auto .44 mag carbine with a new design (along with a .44 lever carbine) a while back and I'd have to suppose sales sucked on both as they were gone within a few years.
Personally, a .357 bolt gun holds zero interest for me. I do own a real .35 bolt gun, in .358 Win and have owned one or two in .35 Whelen. I simply do not see a need for a bolt gun capable to about 100 yards for big game. For smaller game any number of other chamberings would work IMHO. Of course, that's just me...lol.
I have learned quite a bit over the past few years turkey hunting and the majority of it was how to get that tom within range. Every article you read is littered with talk of fighting purrs, flydown cackles and clucks. What they don't tell you is now that you've caught that tom's interest and he's coming on a string... now what? I have seen more blown or missed turkeys from lack of experience in this area than I can imagine. If you can't seal the deal than you may as well have left the...
