ICU, the idea behind a bolt gun as a kids 1st gun is to learn control and discipline. My middle son has a Winchester 190, a semi. When he starts to get sloppy he always changes to my old 1952 single shot, manual cock bolt gun. It is a JC Higgins (Marlin) and he always works out his bugs. My youngest has a Romanian Model 1969 trainer. He is still short, so the small size fits him very well and he shoots it very well. It is a fact that both shoot better w/ a bolt gun and iron sights. If they transition to a semi instead of starting w/ one they shoot that better also. They both love the Marlin 917V I bought for them, yep another bolt gun. They always concentrate more on hitting the target the 1st time w/ a bolt. Semi's are fun, but the disipline learned on a bolt still apply. Starting on a semi often skips some important lessons. One of the reasons so many older .22lr target guns are missing the mag is years ago NRA smallbore only allowed single shot rifles. The Magazines were removed and lost.
