if you are a shooter in the US, and compete in a couple of USPSA practical shooting matches and a couple of Steel Challenge matches a month...

typical USPSA match around here is 125 rounds x 2 a month x 12 months is 3000 rounds a year... for me this is hand loaded 9mm
and small pistol primers are not available

a Steel Challenge match is 5 separate runs on 5 targets per stage x 6 stages per match x 2 matches per month x 12 months is 3600 rounds... for me this is .22lr...prices have jumped from 3.6 cents to 11 cents per round

and that does not include any practice sessions

competitive shooters are not necessarily hoarding components or ammunition, many have stocked deep so they can enjoy their freedom
