Sako 75 Accuracy

I've got a Sako 75 in 7mm-08 that I absolutely love but the dang thing just won't shoot a decent group. I've used factory loads from Federal, Remington, and Winchester from 140 to 120grn. I've used handloads with Nosler BT, Sierra Matchking and currently Barnes X from 130 to 160grn and different powders but don't seem to get this rifle to group better than 1.5 at 100. I've shot a lot of different stuff through it but not a real high quantity, all told probably less than 200-250 rounds.

The barrell doesn't seem to be binding or anything. Aren't Sako rifles supposed to be accurate? The only thing that I can see that may be an issue is the Nikon Buckmasters scope riding on top which will get swapped out in the near future.

Try modulating the takedown torque on the action screw, that can make a difference as the torque is increased and the right torque zone is reached. I had enough of a problem with it on a few rifles that I bought a really fancy torque screw driver. I haven't known that many people that go beyond using what they feel is a good firm torque without over cranking. It's certainly worth trying next time you are out. Start with a nice firm amount, shoot, then simply give it another slightly increased tightening, keep doing it and shooting until it's really cranked. I've had one and a half groups drop to half an inch when they are tightened where they like to be.

Bedding and stock work is the first thing typically looked at in accurizing a given rifle, then action and barrel parameters are looked at for further refining, headspace etc.

I had a Sako .243 Forrester that had just a touch of side pressure on the barrel from the forend out by the end. A little sanding to where a dollar bill ran smoothly under the barrel was all it took to keep it from stringing groups.

I had a Browning A-bolt Micro-Medallion that wouldn't group factory loads. I worked hard and finally found a hand load that would shoot under 1" at 100. I believe I used Winchester ball powder and Sierra bullets but don't remember anymore. The 7mm-08 can be a hard one to get to group in some guns.

I'd try the suggestions above with the rifle also.
