I think James B. said it well
I don't give a hoot about records but animals taken on private land that are free to go anywhere the please should be fine in the books. Fences that hold cattle do not interfere with big game travel.
Now its a completely different deal in my opinion if you are hunting a managed herd that is confined or fenced in. Those records should be for managed game only and not allowed in B&C. and record books like that. Just hunting private land should not matter.
To me it's not the issue of private vs. public, but instead... high-fence confined vs free-ranging. Everybody has their own way of hunting.
