So if this has a rotary magazine, does that make it a revolver?
Okay, the deerfield semiauto 44 magnum ruger carbine actually was released sold poorly and was canceled...and then everyone remembered them so fondly that eventually Ruger introduced a 'new' version of the gun that supposedly worked better with different ammo pressure levels. They also introduced a lever action version.
Unfortunately, the time for a handy little carbine had basically passed when Ruger reintroduced the cartridge. The 30-30 lever actions weren't selling so good, everyone wanted a magnum, etc. The era of the 'practical' mid-range cartridge for whitetail deer was over when Ruger reintroduced the gun. Magumitis had us.
Ruger wasn't smart enough to do a dual-purpose rifle that would appeal to the home defense crowd, fun shooters, and deer hunters. All they had to do was introduce a magazine that held 8 to 10 rounds (15 would have been ideal) and they would have really been onto something...but they didn't.
Now, the Lever Action was mechanically superior to the 'old west' guns...but I guess the people who want lever actions want the TRADITIONAL lever actions, which is why designs similar to the Winchester 1894 stuck around but 'improved' models like the Winchester 1895 or even the 'ultra-modern' winchester 88 or savage 99 couldn't hold on. (and going back to the 'era of practical mid range cartridges for whitetail deer, you'd be hard pressed to be more 'practical' for hunting whitetails than a Savage 99 firing 250 savage)
This is why these two didn't survive.
I think the world is ready for a semiauto 44 magnum and/or 357 magnum provided it is priced a little below an AR, not ugly as sin, and has 10+ round capacity. Without those features those who want a PC-Assault-Weapon are just going to stick with their lever action versions.
This does lead me to an interesting thought. I have heard that many lever action 357s struggle to handle shorter 38 special loads. I wonder if by going to a bolt-gun you skip this problem.
