My question is, WHY? You didn't say you wanted to do CA shooting, which is one of the few places a "single caliber" battery pays off - cheap target plinking at short range.
Why put a handgun caliber in a rifle? I have also done this analysis before. I am in strong favor of the .357 and .44 magnums as handgun rounds, and own guns in each and carry them in town and the woods frequently. But once I go to the extra effort of toting a long gun, I want something that utilizes the stronger action, longer barrel length, and sight radius I now am obligated to carry. A .30-30 is the minimum I would want. And a lever 20" 30-30 is what I put in the scabbard in the far woods.
I don't disagree with the existence of a 357 or 44 carbine - but compared with what a 30-30 will do in the identical platform, why give up the performance? Only to save a few pennies on ammo? If it's a gun for hunting or defense, I thing that's poor economy. If it's purely for plinking or gaming, then it makes sense.
I am not arguing 357 or 44 carbines don't have their place, but analyze your uses before "down-loading" your carbine to a pistol caliber.
