anything from roedeer to fox and from seal to wood grouse. its a potent little cartridge, iirc, they also shoot tiger with the savage.

I would say the Kurz Mauser action in 250-3000 is the rarest of them. the two rifles are only 6000 numbers apart. maybe the owner of the second rifle saw the the other mauser in finland and like it so much he order himself an own.
