Re: how often should i clean my 22
While the barrel of the 22LR gun does get dirty from the firing, it is easily cleaned. Many who have 22's don't ever clean them but maybe once a year or less often. But the problem develops over time if the gun is a semi-auto. With every cycle the gases blow burned and un-burned powder residue into the open action. This gets into every crack and crevasse of the action and over time builds up. You have a choice though. Forget about the junk going into the action and clean it with a complete tear down when the gun quits working or flush and wipe out that residue after each range session. The latter is enough to probably never have to take the gun completely apart to thoroughly clean it in your lifetime. The former should not be attempted without a book or video of disassembly procedures.
For bolt and pump guns little to no powder residue fall inside the action. The barrel and bolt face need to be cleaned but no regular teardown are ever necessary if you buy the gun from new.
Semi-auto pistols and revolvers are very dirty after being shot and need a thorough cleaning by field stripping every time they are used.
I clean my guns after every range session. There are NO dirty guns in my safes. Regular cleaning minimizes or eliminates the need for complete tear downs for cleaning.
Just like there are different opinions about how often to bath yourself, so there are different opinions about how often to clean guns. For me cleanliness is next to godliness.
