I've cast/swaged a couple of different bullets that were hb bullets in the same weight range (110gr to 130gr) for the 38spl's & 9mm's.
What don't want to do is cast them with too soft of an alloy. You'll get into the blow the skirts off territory/game. I cast mine out of 8/9bhn range scrap and water dropped them. Water dropping them helped protect the hb bases from getting deformed and brought the bhn up to 11/12bhn.
As far as data goes, use the lyman 358091 wc data & work up for accuracy.
Starting loads
700x 2.9gr
bullseye 3.1gr
titegroup 3.1gr
AA#2 3.1gr
231 3.7gr
unique 3.7gr
clays 2.7gr
reddot 2.8gr
N320 3.1gr
zip 3.5gr
When you're not sure about a bullet/load combo, look around. Speer uses a heavier 148gr soft lead swaged hbwc that is seated flush. Heavier bullet, seated deeper made out of a softer ally.
Max loads from the speer manual for the swaged 148gr hbwc seated flush

I've been thinning the herd of hb molds I have, down to 12hb molds that cast bullets for the 32cal/35cal/41cal/44cal/45cal's. I shoot more of the Mihec 148gr hbwc/american select (3.0gr/13,500psi+) combo then the others. Need another #4 jug of am select (9,000+ rounds per jug) or I might switch to clays.

Don't be afraid to heat your hb bullets up. There's a huge difference between a soft swaged lead hbwc and your cast hbwc's. Did a little testing with cast hb bullets in a snubnosed 44spl.

The bottom left & top right bullets are 2 of the main bullets I use in that ca bulldog. The top right bullet is a Mihec 220gr 44cal hbwc that was cast with 8/9bhn range scrap &water dropped making it to hard/brittle & didn't expand. Same bullet/load, this time the 8/9bhn alloy was air cooled.

The top left bullet is a lyman 429422 hb swc that was cast out of 8/9bhn range scrap & air cooled. Then a forster hp tool was used to make the hp. The bottom right bullet was cast from a raphing hb fn mold. I initially cast some air dropped 8/9bhn bullets for the test along with pc'ing them red. I already had some 15bhn/water dropped bullets cast & coated red. Of course I grabbed the super hard bullets and used the foster hp tool to hp them. The recovered bullet didn't even deform but it did go thru 12"+ of wetpack @ 25ft.
Why all this?
Because with my cast hb bullets I run them in the 13,000/14,000psi for target work & +/- 18,000psi for sd loads.
Like I said at the start of the post, I'd use the 358091 starting data.
