quote;"the scope mounting options are limited"
The Tikka can/does use proprietary factory rings to fit the dovetailed receiver. But, they're also drilled and tapped. Weaver, Burris and probably Leupold make bases to fit . The Weaver Grand Slam bases are steel(part no. S61). So, while you won't find a picatinny rail for 'em you do have a fair number of options out there.
FWIW--- Every Sako product I've owned has performed very,very well.
