I was talking with one of the guys at work today about teaching kids to shoot. His are 7 & 9, mine are all older, the youngest is 16 this year. We were discussing what rifle to use. I recommended he buy them 10-22s, get take-off wood stocks off eBay, and shorten them to fit. He was concerned with giving them semiautos. I told him that it wasn't hard when mine were little, to block the magazine so it would only accept one round. But, Ruger now sells single shot magazines. At that point I think I convinced him to buy them 10-22s. The single shot magazine is the BX-1-1, Item Number: 90344. They are available from Ruger at shopruger.com, but you can probably get them for less through other sources. My daughter would get terribly frustrated by the one shot magazine I made for her to learn to shoot with. Her big brother had his own 10-22, with two stock magazines, and she was using mine with a cut down stock installed, and a magazine I had modified to hold only one round. We shot juice boxes I bought for 10-cents each, at Wallmart. Which if your teaching kids to shoot is an ideal reactive target. At 25-yds, they explode with a nice splat noise, when you hit them. And, spray brightly colored fluid all over. Highly exciting for the kids. I also use them when shooting my 204 at 300yds. It is really hard to pick out 0.204-inch holes in targets, that far out, but the juice boxes present a 1-1/4 by 2-3/4-inch target if you set them up with the top facing the line. When you hit one with the 204 they quite literally explode. The rifle had a bipod on the front, resting on a bench, so she didn't have to support the barrel weight, but did have full control of the rifle. She was getting pretty good after half an hour, but she really wanted to shoot full ten round magazines. So, I told her that any time she hit ten in a row single shot, she could shoot off a full magazine. After that she got serious about making every shot count, so she could get a full magazine. The first ten rounder, she fired off her ten rounds as fast as she could, but only hit one juice box. By the third ten rounder, she had figured out with only a little encouragement from me, that it is a lot more fun to slow down and hit the targets, than to rapidly launch bullets down range without hitting anything.
