Stovepiping due to loose handling (limp wristing) of the firearm, use of poor quality ammo (particularly, poorly done reloads and use of cheap ammo in firearms which are picky about ammo), poor maintenance of the firearm, incorrect assembly of firearms built from components or parts kits.

smokestacking gunsmith term

The term is actually "stovepiping", and causes vary far and wide. Short stroking of the action due to an improper fitting in the gas system might be one reason, or it could simply be a weak extractor. It may be an issue of difficult extraction due to residue in the chamber (especially if you're using lacquer coated ammo, or have used it in the past without cleaning the chamber).

Tentatively, yes, although you should refer to the owner's manual for the manufacturer's stance before doing this. Depending on what action and feed system your rifle is, you may not be able to get .22 Long cartridges to feed from the magazine. However, if your rifle has a tubular magazine, this should not be a problem. Another possible problem to consider if you're using a semi-auto rifle is the possibility of short stroking, which may lead to stovepiping of the spent casing as it is ejected.

Yes. However, whether the firearm can feed the .22 short rounds depends on the feed system and action of the firearm. If the .22 LR is fed through a box magazine, the feed system isn't likely to work with .22 short. Lever actions with tubular magazines and breech loaded weapons can typically fire the .22 short, .22 long, and .22 long rifle cartridges. In the case of a semi automatic with a tubular magazine, the .22 short may not produce enough gas pressure to cycle the action. Dependent on the rifle, it may cause short stroking, and could lead to stovepiping, or it could just simply require the action to be worked manually.
