Repalcing rear sprocket

[Reddog74usa]

I removed the sprocket off the brake drum and was wondering if anyone had some good info on the best way to set the rivets. The rivet holes in the drum are in perfect condition and not egg shaped. In fact it looks like this is the first time the sprocket has been changed on this drum. I have a press and also an air hammer but was thinking about just doing it the old way with a punch and hammer. This drum is real nice and I don't want to mess it up any ideas?

The last time I did it I had to hammer them with an anvil underneath, the rivets are soft enough to peen over pretty easily.
