What's wrong with linseed oil?
Everything!
It is a good finish IF high grade oil is used properly. Just blathering it on a stock after the fact, no matter how carefully you think you cleaned it off, is a huge mistake.
BLO is great on axe handles.
I have a walnut stocked gun, I bought new early 60's, that came with raw wood, no finish, that would argue that.
To each his own.
