Well, Alan, as far as I know Cooper didn't make scabby old wartime rifles which were later sold by the crate load. So that WAS irrelevant.
I didn't know about the @ thing, so thanks.
Anyway, OP, I bought a rough Cooper M22 and had the synthetic 'Phoenix' stock repainted in Ceracoat, which went well. It's a fairly stiff stock, marginally low in the comb for me (but most things are). The bedding compound beneath the front of the action was strange flexible stuff which was easily cut out and replaced with Devcon. The trigger was creep free and came to me at 1 1/2 lb, if memory serves. I didn't adjust it. It came with bases for Leupold rings. I had a Sassen tube in Rem Sendero profile fitted. It shot beautifully, after a bit of careful load development. I sold it only because I got the chance of something even nicer and couldn't justify two 6 BRs. I know the new owner loves the rifle.
I understand Muir's point about a lack of back up- but don't know how often you're likely to need anything for one- If you were unlucky enough to need the odd spring or an extractor, there's plenty of talented 'smiths here who could make them or modify something similar to fit, so if you have your eye on one, I wouldn't let that put you off. Lots of rifles in daily use have no back up as far as spares are concerned, but keep knocking stuff over just the same.
As an aside, I see from the Cooper website that their range has increased considerably since Fox Firearms last imported Coopers to the UK. Some of the stainless stalking rifles take my fancy very much indeed.
