hello, im new. i still have to go through the waiting period but i own a m12 winchester. i have never used a pump so im wondering if some folks here can help me out with the operations manual [not on winchester site] or just such general informational things like how to properly load/unload, clear a jam, field/detail stripping, what parts to clean & oil, what happens upon "short shucking" and what to do if it happens?, etc. thanks.
