3 reasons that I can think of .
1 cost , most of us hunter are cheap
2 weight that laminated stock weighs more and I have been told that there is too much taken away in the wrong spots to use walnut or other woods.
3 Stuck in the mud , that stock is to wild looking or it's not like my dads.
I like the looks and feel of a good thumbhole sthock ,got 1 on a tricked out 10/22
