It seems silly to me to engineer a break-action rifle platform from scratch and only offer one rimmed caliber (.44Mag IIRC). Surely they would be open to at least a .357 Magnum version, of course that's easy to say when they'd have to source an entirely new line of barrels and extractors for .35 caliber rimmed. What I was hoping Henry would try to do was fill the niche that H&R has left open: An economy-grade, switch-barrel, break-action with a barrel exchange program and about 20 calibers offered, but this does not seem to be the case so far.
I want to see them re-produce the Colt Lighting in .38 Special, .44 Special, and .45 Colt, but I don't think they'd be able to do it at a price point that would be affordable enough to generate the sales required to net a profit in the end. Henry's own designs are streamlined for production and economy, hence the relatively low price points.
