You have your common (standard) calibers such as .45, 9mm, .22lr, .30-06, .308, .338 and so forth for rifle and pistols.
However, there are new calibers being made all the time and even older ones are gaining newfound popularity, especially in the AR15 platform such as .300 Blackout, .300 Whisper, .204 Ruger and others. You're seeing new rifle calibers such as the .26 Nosler, .28 Nosler, and now . 30 Nosler.
I can't think of any newer pistol calibers but the old .380 has quickly become more popular due to so many people with carry permits including women.
I know the general rule when I was younger and buying a rifle was buy a rifle that can handle anything you ever think you'd hunt (for me it was elk on down), in a caliber that can be purchased anywhere because if you do hunt out of state and you need to pick up ammo you'd most likely have a limited selection at small local stores and would want a common caliber that most people carried such as .308, .30-06, and .338. It would be a bad idea to purchase a rifle in a caliber like .300 Blackout because if you lose your ammo and need to stop at Woodland Sports and Gas in the middle of nowhere they are most likely going carry those common rounds and not the .300 Blackout. I know at most small stores you could find 9mm and .45, although .380 could be hard to find in many stores still despite it's popularity.
With the advent of new calibers occurring all the time do you see any rifle or pistol caliber/cartridge becoming a common one or have all the common ones already been basically set in stone.
