Hi guys,
I'd either use the Mauser DSM 34/Mm410b action (the "B" series), or the Kimber K22 action (which was based on the Mauser). I'd choose it because it has controlled-round feed and has a timeless quality.
For a look at my ideal .22 sporting rifle, have a look at this Dorleac and Dorleac rifle:

I've posted it elsewhere, but...
Spikey.
EDIT: My apologies - I forgot about the"production" part. Sadly, both the Mauser and the Kimber are no longer made.
