Ok Ive been working hard on loads and shooting and the best I can do consistently is 1/2 grouping. I'm pretty sure this is the best I'm going to ring out of this Tikka varmint 22-250
My dilemma is I want to order a krieger barrel but not sure I want to put it on a tikka I like the smooth action and smooth factory trigger. it shoots well for a stock gun but there's something about the cheep recoil lug that worries me a little! its a square piece of removable aluminum that sits in a grove in the action and stock.
Should I re barrel it or find another action?
Should I keep it in 22-250 or go .243AI or 22-250AI I'm not into speed I just want a 1/4 group gun that will feed from clip dependably for hunting. I have two of these Tikkas now another in .243 pencil barrel

Sell the tikka and get a Stiller action - would get you closer to your goal with an action designed from the outset for accuracy.

I agree
If ultimate accuracy is your game, then you need to start with everything aimed in the right direction. The Tikka's a great hunting rifle (1/2MOA) but you'll probably not find too many on the bench rest circuit.

A good book on the topic is "Precision Shooting at 1000 yards" by Dave Brennan
