Depends on the stovepipe. Was it an empty and a loaded round? If so, your ejector is bad. Typically, if they die, the empty case goes up into the slot in the bolt handle. Aggravating. Take the bolt apart and clean it, inspect for broken metal. If it keeps up, there is a product called a Defender Ring that will help.
If two live rounds, your mags are the culprit. Get a Colt or standard GI mag and see if it helps. Change mags and ammo before you start overhauling the rifle.
On the .22 questions, before I bought a Mosquito or a Walther, I would get a Ruger Mark III. Both the Mosquto and Walther are hit and miss. Some run, some don't, and no apparent reason why.
In order to properly convert this thread to a polyasshat thread to more fully enrage the liberal left frequenting here...... (insert latest democratic blunder of your choice).
