Can't say much about the 22 mag because I don't have one. I do own a Henry .22, the H001 and it has been great for the last 12 years of steady use.
If they are still making them as they did 12 years ago, you will have yourself a good rifle. I can impress myself with the accuracy I can get out of mine. The action is smooth.
No problems with mine. I am not sure about the plastic parts on it someone else mentioned. The butt plate and the tip on the inner mag tube are the only plastic I notice on mine and neither have given me any reason to be concerned about them wearing out. If the inner mag tube ever does mess up, Henry sells them for $21.
