What's legal size for Moose Olddude?

Just about to go on our Elg hunt in October- the landowner and the Norwegian Wild Life authorities tell us what animals are on our ticket. We normally have five allocated to our group for the week (mature bull; two one and a half year olds; two calves) It is very rare to get a cow and they prefer it and we agree that any orphaned calf on is preferable toto shoot as it would not survive the winter, or one calf from pair of twins - never a single calf accompanied by its mother.
