Is there another way ? I've had to check a brand new 90 myself only a few weeks back in the same cal.

It was offered with both twist rates, depending on whether it was early or late production. Serial number lookup might help you, but Sako s/n's are unreliable. Cleaning rod is the way forward.

That'll be a 11 more likely than 10 then. The rod method underestimates rather than the other way round.

You might also want to try getting the rod a little further into the barrel before fixing your reference point. I found that helped in the past

darn new high BC bullets and older slow twist barrels . I am wanting to use the 175 gr terminal ascent
It's lenght is 1.510 and concerns me for stability
