I shot one night a week with my wife, then every Saturday with her and on Sunday by myself. I went through a brick and a half each day. Sometimes more/sometimes less.That is more than 250 rounds a day.
My wife went through a half a brick per day that she shot.
This was in the "good old days" when both K-Mart and Dick's had sales on .22 ammunition & you could pick up a brick for ~ $7 or $8. We'd each buy the 10 brick limit, then hunt down a different store & buy 10 more each.
We pretty much kept a stock of 50,000 rounds on had at all times, just so we had enough to keep having fun!
The downside of all that was the lack of trigger time many of my other guns missed. Oh well, can't undo that.
The Ruger really handled it well though. Outside of a very, very,very, very small blemish on the barrel - the gun looks perfectly brand new.
I have a twin to it that has less than 1000 rounds through it & you really have to look hard to see the difference.
I bought the newer one ~ midway through the marathon - after I'd grown respect for the Ruger & half way in fear of it "shooting out". My fears were foundless though. The gun is fine. I've only put a few hundred rounds through it since that year though.
