I dont have a Handi in 30-30 but I have a bolt action Savage 340 chambered in 30-30.  I load 110 hollow points at close to 2900fps, 125 Noslers at 2700fps IIRC, and my own  cast 172gr pointed gas checked bullets at 2600fps.  I just use the date they have for flat points but start low and work my way up, ussally way up.
I like pointed bullets in my 30-30 but being a bolt action it is a whole different game, with a Handi you can set them longer which might be a good thing.
