What is the factory muzzle diameter on Ruger 77 MK/II rifles?

What would you guys recommend for a lighter contour 22” barrel on a Ruger 77 MK/II?

How well does a lighter barrel balance and look on them? Pictures of your rifles with light weight barrels?

One 06 and one 270, both measure .533 on mine.

That's thinner than Winchester Featherweight contour.
For reference I have a new Rem700 30-06 24" and it's .670 at the muzzle.

I like the Bartlein contour chart.

I know it's not the most accurate way to measure, but, three trips on and off the bathroom scales each with and without barrel in hand, 1.8#'s (176.2 and 178)

Not much need to look for a lighter contour in my opinion.

Thanks guys!
