I took my son to the range Saturday so he could shoot his new Sportster 22LR. I was shooting my Sportster 22WMR (still working on a card for the postal match). When we were packing up, the guy shooting next to us says to my son..."I've been looking at your targets and your doing a great job, would you like to try shooting my gun?" Well, he would never pass up a generous offer like that, so this guy loads up two magazines for his Bushmaster .223 (about 20 rounds in each mag) and lets my son shoot one of them, and I take care of the other one. I've found that the guys at our range are always very friendly and willing to help out whenever we have a question or need something, especially when my son is with me.
Here's a picture of him shooting his Sportster, and one of him shooting the Bushmaster:
