if you make a trip to SW Houston, I can help you support your daughter.
I've stumbled across 22lr three times in the past 2 weeks, so ... I can share my good fortune.
Or, take her to Top Gun. They will sell you 2 boxes (100 rnd CCI Minimags) on your way in with a lane rental. I also found minimags at Carter Country in Stafford - limit 1 box. And, Remington Hypervelocity at Fountain Firearms - limit 2 boxes (they also have a good selection of subsonic 22).
