I can fully understand the idea of limiting calibers. It makes perfect sense to do so. That's why I have committed to having no more than 35 different calibers. It makes things so much simpler.
Well yeah, you have to draw the line somewhere!
I have chosen to primarily go with calibers in use by US Mil/LEOs so that if some crazy scenario should ever happen, I know there is a large stockpile of usable ammo. But this is really not helping me with my newly rabid desire for a 1911, nickel plated, in 38 super. Or that .44 redhawk. Or the 45-70 marlin. Or... dammit, this plan isn't going to work out long-term is it? Lol.
