Methinks a re-purposed 2.5mm drill bit shank will keep you extracting.

NB this time, keep it clean and oiled. (-:

Cheers 10x over. I was going to go see Mark at Waitaki engineering but I like the drill bit idea as it fits the rifle well.

And yes, cleaned and oiled. I actually get quite upset when my guns are not oiled, so it never happens in normal proceedings. The eezox is out in force right now.

My must dog know how much I like it because for reasons known only to him he has rolled in my oil rag and now smells like eezox.
