Lets put it this way, my Sako m75ss 22-250 I bought recently off a fellow member shoots 0.371"groups (outside-outside) with factory Winchester 40gr cheap ammo. Now wait till my reloads with 55gr.
I have no doubt a Sako m85 Varmint will be a shooter. There was a CGNmember that had a Sako m75 Varmint 22-250 listed in the EE posting his groupings.
