This stock was returned to Cali'co because of the spots at the end of the fore end, circa 1997. Cali'co replaced it with a new stock blank and sent both pieces of wood back.
If I was going to build a Sako-actioned rifle today, I would use this in a heartbeat because the spots have no effect on action strength/stability and I see them as unique character marks in the wood.
Trouble is, I won't build any other left hand rifles, (let alone Sakos) which was the only reason I used a Sako action vs. a P-17 action for a .495 A-Square to begin with.
This stock blank was cut at A-Square and this has a butt pad that is 2.25" Wide x6" Tall. This was known as their "Coil check" stock pattern and spreads out the recoil force quite well.
