I was being conservative. 12,000 is not too much. I think it goes to the mix. I have a good mix of 9mm, 10mm, .45 and .357 handgun wise, although I have carbines. From a survivalist standpoint, 2-15,000 .22 LR falls into its its own category. shotgun, you have to factor your own plan from 7 1/2 to slugs. Defense/assault/big game, you consider your equipment for .223/.556/7mm/.308/7.62/30-06 etc.
