The only remedy was a strip down where following removal of the pellets gathered in the end of the cylinder all was well.
Yours sounds like it has this problem?
That would be my suggestion too, my first Goldstar had a small pile of hammered pellets sitting in front of the sliding cylinder, it happens on both .177 and .22 rifles.
