By "almost in contact" I mean less than the thickness of a piece of paper clearance or barely contacting. The ejector is adjusted by (carefully) bending it. I adjusted mine and have adjusted the ejectors for guys with 15-22s at my home club. I'm not parroting what I've read...

After 5 yrs of shooting Rimfire and Steel Challenge and Bowling Pins Matches (and lots of practice rds) I still have the original extractors and springs and plungers in place. My 15-22s are EXTREMELY reliable. The only other reliability change I've made is that the Giessele triggers I run have extra power hammer springs and I use Colt 901 trigger and hammer pins that are longer and sit flush with the outside of the lower.
