That looks(and shoots) great now! I've done several crowns with hand tools only- the latest was removing muzzle threads and recrowning my 6.8 AR barrel. A smooth exit point for the bullet is all that's needed. I've never gotten Less accuracy from re- crowning.
Sandvik hacksaw blades were preferred, but I haven't seen any of them in a while
