and having lots of jams, failures to feed and fails to eject. I asked what he was feeding it; Remington bulk-pack. I had a baggie with some Federal bulk-pack hollowpoints and suggested he try them. BIG difference, it ate three full loads of them with no problems.
Moral of the story: any .22 autoloader that has feeding/ejection problems, try some different ammo, as some will eat anything and some can be remarkably picky.
I'll throw in, when friend gunsmith gets in a .22 of any type that's having those problems, first thing he does is field-strip and clean the hell out of it, which solves between 50-75% of the problems; .22 ammo tends to be a bit dirty, crud builds up under the extractor hooks, in the chamber, etc., and sooner or later causes trouble.
