Brass is reuseable, ignore that and your at a dime a round.
In the realm of .22lr, only with a whole nother level of THUMP!
You give me a choice between 10 rounds of .22lr and 8-10 rounds of reloaded centerfire.
I'll take the centerfire, most of the time. But once in a while it is just fun to shoot 50 rounds of .22lr through the Ruger Mk III 22/45's. Not as much thump, but the precision is fun.
Put 4 dots around the outside of the target at 3, 6, 9, 12. Then go run the bases.
As fast as you can put 10 downrange and still hit a 1" dot 3 out of 4. Pushing for speed, 12, 3, 6, 9, round and round.
Run a couple clips like that. And then look at those groups.
Get a target like that with tight clusters of holes you can cover with a pop bottle cap, where you know you were faster than 10 shots in 15 seconds. Builds confidence.
