Its kinda funny, there are certainly cartridges whose popularity has me scratching my head, particularly when you consider some of the pretty good ones that have dropped off the radar. The .32 Winchester Special, a black powder hold over, comes to mind, as it does nothing with smokeless propellants that a .30/30 doesn't do as well. I've never much liked the idea of the 8X57, first due to the fact that they couldn't decide if it should be a .318 or a .323, and then when they did choose, they went the wrong way! To my way of thinking, the older 7X57 has the 8mm beat in every way you can imagine. Then there's the .30 Carbine, which never was a decent rifle cartridge, but seems a bit much to enjoy from a handgun; I guess that's why its called .30 Carbine rather than .30 rifle or .30 pistol. I grew up having more disdain for the .270 than I ever had for the .243, although I've since come around. But when I get the chance to get behind a rifle chambered for one of these turkeys, none of that matters. I just enjoy putting rounds down range, and experimenting at the loading bench to see what works and what doesn't; the lettering on the headstamp just doesn't seem to matter once my interest is sparked.
