Stevens manufactured the Sears 2200 semi auto in the early to mid 1980's. Stevens recalled certain models in 1982 for inspection due to a possible safety malfunction at no cost to the owner. Serial numbers recalled were B256621 or higher, C000001 or higher, D000001 or higher. The number you have provided is not a serial number but looks like a Sears part number.
Offhand, probably a sear malfunction, assuming you haven't previously made trigger adjustments to it.
The question can't be answered without a detalied description of all markings.

If you are asking about the 2200 Crosman Magnum air rifle then it shoots a .22 caliber pellet not a BB.
