When I was shooting IPSC and CAS competitively, I was typically burning 15,000 to 20,000 rds per year. These days I don�t shoot competitively and I don�t shoot nearly as much centerfire stuff. I mostly practice with .22 rimfire, burning a few hundred rounds each time and just a little centerfire stuff. I use .22s as surrogates for centerfire guns doing most of my practice with them. I keep a pretty good stash so I don�t have to go looking for it and can ride out the panic buying in times like this. I shoot the .22 stuff for practice because I�m not that wild about reloading, and it saves me a bunch of time.
