The shame of it is that it does not currently have enough support to be successful.
The guns are hard to find, and the ammo is also hard to find. That is NOT the way to launch a new caliber. But then again, maybe this is the choice of the folks who are purchasing the guns & ammo for the stores, and not the ammo or gun manufacturers themselves.
I was pretty closed-minded at first, but it seems to have a lot going for it: High energy, but low recoil, extra capacity.
I may have actually turned around 180° and bought my SP-101 in 327 Magnum instead of 357, but guess what? None of my local stores had ammo or guns in the caliber.
A few more guns chambered in that caliber wouldn't hurt either. Like a Single Six, Marlin 336, etc. One member here made a good point about it being a good field cartridge, but no "field guns" are chambered for it. It can & will succeed, if it is given proper support. It just seems like it has been kind of a half-hearted launch effort.
