Caliber or calibre is the approximate internal diameter of the firearm barrel, or the diameter of the projectile it fires.

I thought this might be interesting — to discover what the most popular firearm caliber choices are among those who choose to comment. Be it a handgun or rifle, what is the caliber of the firearms that you own? Feel free to post anonymously if you wish…
