I've had guns since I was a kid shooting groundhogs, rabbits and pheasant on the farm starting late 50's. Life happened... military, career, kids etc etc. Now in my 60's and retired, I started a more serious gun collection a few years ago. My goal was to have at least one gun in every "major" or "common" caliber of handgun, rifle and shotgun. Below is my current list of calibers. What I'm interested in from the forum is... are there any "major or common" calibers missing that you think should be on the list or any that you don't think fit the "major or common" category? Obviously this is subjective, as the very words "major or common" are somewhat nebulous. I don't know how else to categorize a caliber though... maybe number or guns made for that caliber? How does one find that? Going down the list of calibers at online ammunition retailer has EVERY caliber available, so not much help weaning out obscure or uncommon ones. My WW2 guns like my Arisaka or Carcano of course would not fit the list of "common" today, but I wanted a major rifle from every player of the period. So other than those two... any caliber I should add to this collection? Other than the two mentioned above, any so "uncommon" I shouldn't call it common? Again... somewhat nebulous question, but looking for some sense of order and classification.
