I always welcome new cartridges, even though I often don't get excited about them. I suppose some of the concern for a prospective buyer is whether or not the cartridge will endure and be supported. The 17 Mach 2 was a real winner, but for some reason or another is no longer chambered by anyone other than Savage as far as I know. If this one turns out to be a winner, will int continue to see support?
