If memory serves, Hart produced rifles with two and three layer laminate stocks. With stable and dry pieces, gluing them together with cup (growth rings in plain sawed boards) sides facing each other it should work fine. Given that Hart used thick pieces, I wouldn't say that coarse laminates can't be as good, but given the standard now, and my observations I tend to agree the thin layered laminate is superior.
OP: If I had some stock slabs, (or a suitable log species ready to cut) I could probably set you up with a rough sawn piece for a reasonable price. Box stores probably will only have plain sawed G4S for at least $20/board foot. I've been hoping for a Black Walnut tree from which to cut some choice slabs to age... so far I'm being deprived.
Where in southern Ontario? Local lumberyards would be most affordable provided they have 2"X6"X3' pieces (or longer) of specifically American Beech, White or Yellow Birch, Red or Sugar Maple. If you want something soft to carve, (albeit plain) but that could be satisfactory stock, Basswood... it lacks the strong odours and pitch associated with conifers.
