First, remove the perfectly effective scope and cheap but effective mounts from your rifle.
1. Source an excellent replacement scope and realise it's a different tube diameter
2. Do the right thing by your Finnish rifle and decide on Optilock mounts
3. Make a semi-calculated but ultimately wild stab in the dark at the right height for the rings for your replacement scope's different objective lense diameter
4. Wonder momentarily at why Sako decided to saw a perfectly good mount in half and fasten the rings to the bases with a floating fit
5. Work out a way to assemble the rig loosely to get crosshair alignment, eye relief and recoil lug placement correct before nipping it up
6. Fail to work out a way to achieve the above
7. Work out which bolts to apply Loctite to
8. Undo everything you've just applied the above to because when you tightened the rear scope clamp it pulled the crosshairs to the right/left/right again/ left again (repeat ad infinitum)
9. Get the clamps set right, then realise you need to undo the bases to Loctite the unnecessarily-sawn-in-half rings to prevent the effing scope leaping off the effing rifle
10. Tighten up
11. Peer through a scope picture that looks like a periscope on a rolling sea
12. Sprinkle with vinegar, season with freshly ground black pepper and toss it in the bin as good for nothing (with apologies to Dr Johnson and none whatsoever to the vodka-soused lunatic who whiled away a Scandinavian winter deciding how much fun it would be allowing everyone to spend six months of darkness fitting a single telescopic sight)
13. As long as the deer lean to the right, they don't stand a chance.
