extractor has good tension & I can't see any damage on those parts.
I had a hunch that the spring might be the culprit here and I guess I'll have to try a new one. I think the standard is 16 lbs.(?), would it be wise to go for a stiffer spring?
Might as well try opening up the ejection port. The ammunition has been consistent and I do check all those things frequently, and this ejection problem has occurred with factory hardball ammo as well.
Thanks to all of you!
