Wondering what folks think. I'm planning on buying a Sako 75 Hunter in 300 Win Mag and mounting a Zeiss Conquest 3.5-10x44 scope. I'm planning on getting the rifle with open sites and the option of the oil finished stock instead of the varnished.

Questions:

1. Is this an appropriate powered scope for this rifle?
2. Will the open sites interfere with scope mounting?
3. Any thoughts on oil finished stocks versus varnished?
