Old hard or Yellow pine framing lumber from the 1950s and further back is very hard to drive a nail. I have never seen framing lumber milled from anything but a conifer tree. That's just me. I have seen pallets made with scrap maple and oak. Pallets are very hard to get apart because the are nailed with twist nails.

Well,barn wood support beams are old oak and such. A lot of those old barns were drilled with a brace and bit and “pinned” with dowels. It depends on your area for old lumber. I was talking about South Jersey.
