I recenty bought a golden boy 17hmr which has an ejection problem, about every tenth round fired, the casing sticks in the chamber, and the ejector arm hook slips over the rim trying to pull it out. I cleaned and oiled the heck out of it, which does help a little, but it still does it. I looked at the hook on the ejector, which is sharp, and should grab the casing. It's one of the smoothest and straighest shooting guns I own so I love to shoot it, but this is a big pain in the behind. Any one else same problem, solutions?
