Heavy pistol powder in 500 Linebaugh

[Bigbore5]

I have a few kegs of Shooters World Heavy Pistol. It's really Lovex powder. Usually I load most my 357 mag with it and it works fine.
This powder is comparable to AA#9 in burn rates. Since it is meant for large capacity handgun cases I'm thinking it may be suitable for the 500 Linebaugh medium heavy loads like #9.
Has anyone tried it in the 500L yet or if someone has quickload and could check for a starting load with the CP 435gr wfngc bullet and let me know I would deeply appreciate it.

I did not find a 435 WFNG in Quickload so I took a 450 and "tweaked it". The data below is for a 0.613 seating depth. Also note that Quickload is typically considered less accurate than desired for predicting pressures in straight wall cases. Out of caution, I ran a table, but let it end a good bit before getting to max rated pressure.

Thank you very much. That gives me a good place to start. I'll try to stay below 35,000psi at the top end.
