That caliber seems to have faded away, even moreso than the 358 winchester and 35 Whelen. It'd be nice to have a 308/30-06 based non-belted non-magnum cartridge above thirty caliber. Other than the Browning BLR and CVA Scout I can't think of any currently produced rifles in that cartridge class, although CZ does chamber in 9.3x62, which is similar.
The problem with pet rounds is that everyone has a different one. Some want a 257 roberts, some a 6.5x55 (or 6.5 Grendel), some a 7mm Waters, some a 338-06, some a 358 winchester, and some want somethimg even rarer. There's just not enough demand to justify some of these niche rounds unfortunately. It's a real shame, as some of these rounds fill a real niche. For instance I'm fond of the 358 Winchester, what caliber could be better out to most people's ethical hunting range of 200 yards?
