I agree with the last 2 posts. If you love it and it does everything asked of it, keep it.
Maybe get it re-crowned, action bedded, cerakoted to bring it back to former glory (gloss socom blue
) and you can lavish some time and tru oil on the stock.
Then you have a new looking rifle but all the attributes of the old one. Like an old friend in a new suit.
Or get her rebarrelled, do the above and have hundreds of quid in a rifle worth very little. But she is yours and you love her
If if that's not an option, depending on budget, go Howa, Tikka, Sako or CZ. You even keep the mauser action with the last choice.
All good brands, pick a few you can afford then research the hell out of them and whittle out the less than perfect ones.
