CZ 527 in 762x39.
Cheap and accurate and it will do fine under 200 yards on deer.
I’m actually thinking of using for elk one of these years.
Obviously I’d be limited on distance but Ballistics are close to 30/30. So it can’t be that bad
So many good calibers out there.
6.5 Swede, 6.5CM, 7-08, 7x57, 270, 280, and the list goes on.

All of them do something better than the 30-06, but none of them do everything as well.
