Well, there are gun owners, gun enthusists, hunters, casual shooters and then competitors. I doubt the average US gun owner goes through even 50 rounds a year. The avid hunter might go through a few hundred rounds a year. There are competitors who go through well over 100K rounds annually. The average 3 gunner/USPSA pistol competitor is probably in the 10K range...half are shooting more and half less, but that is a LOT of ammo.

On December 15th, my family went to the range to shot steel challenge...we went through 1200 rounds in one day! I try to keep about a year supply on hand, but if this keeps up much longer, I will have to dig into my supply or cut back on shooting matches...already cut out the live fire practice.
