This would be a huge hit in 357… dunno why they never did.
Agreed. Like the 10/22, the .44 Carbine was inspired by the very popular at the time M1 carbine. But I suspect Ruger shied away from .357 Mag for a couple reasons:
- Ruger, and Bill Ruger in particular, saw it as a short range semi auto deer rifle, where .44 Magnum was perceived as a better choice than .357 Mag. They never really saw it as a plinking rifle, or of they did they felt they’d be competing with the much less expensive surplus and commercial M1 carbines.
- While the .357 Mag is better than the .30 carbine in many respects, the .357 Magnum performance in a carbine isn’t that far above the .30 carbine. The .357 Mag launches a 158 gr bullet at similar velocities to the 110 gr .30 carbine, so it wins on bullet weight, energy, momentum, and unexpanded diameter (as well as expanded diameter particularly given the limited expanding bu,let options for the .30 carbine). However, the .357 Mag doesn’t shoot quite as flat or quite as far as the .30 carbine with its higher BC bullets, was never going to compete in terms of magazine capacity, and ammunition was a lot more expensive when you could find Lake City surplus .30 carbine ball ammo for $5 or less per box.
Living in the big high plains states out west, I didn’t have any need for a 100 yard deer rifle in .44 Mag, and I already had an M1 carbine and 10/22. However, I’d have bought a Ruger carbine in .357 Mag in a heart beat as it was IMHO just right as a powerful but not overboard, flatter shooting 100-150 yard mid bore round with much better expanding bullet choices for hunting purposes than the .30 carbine.
While they had reasons that probably made sense at the time it was introduced, I still think Ruger missed the boat, and a major market niche, by not offering it in .357 Mag.
Today, you can find a number of lever action rifles in .357 Magnum as well as .44 Mag and .45 Colt, and the .357 Magnum is the most popular of the bunch as it’s again a right sized mid bore round with a great deal of flexibility.
