I actually follow that thinking to some extent. 5.56 and 7.62 for centerfire rifle - not going to mix those up, .22LR is all by itself. Mostly 9mm for pistol rounds, although I do have some .40. All of my go to pistols are 9mm. Yeah, there's a .38 special around here somewhere that was given to my wife by an old police chief friend of mine years ago, but I don't see ever using it for anything I can think of. She's a .380 gal and I don't see me every changing that.You could find yourself holed up with some weapons, but out of ammunition that fits them. Ten is none?
I was thinking a variety of weapons accepting same cartridge would be useful. But doesn't meet all performance needs. Would want to minimize number of different caliber.
I like the thinking of the 9mm carbine for this reason but I haven't bought any yet. Effective range of 100 yds is a little better than pistol but part of that depends on how good you are with a pistol - and which pistol. I'm also a fan of sticking with calibers which are prolific, ergo easier and cheaper to acquire ammo for.
