9.3x66 Lapua type of caliber of it's era in 1910-1930's, 9.3x63 Miller & Val Greiss, made by surprise as signed on octagonal to round full length raised matt sighting rib 'MILLER & VAL. GREISS KGL. BAYR. HOFGEWEHRFABRIK - MUNCHEN'. Having a bead fore-sight with flip-up moon-sight, rear-sight with adjustable standing leaf for 100 and 200 metres and folding leaf for 300 metres and fitted with a Voigtlander Braunschweig 'Skoparette' 4x telescopic sight in quick detachable tunnel claw mounts and also with a sprung aperture peep-sight on the tang. No need to purchase a new Sako on 9.3x66 Lapua, do have my challenge already to get the ammo's for this one, well a positive problem with this rifle I've to say.
