Quickload help please

[zacmando]

I have a .280 AI that shoots one hole with a 140 grn tsx and RL-19 powder. I want to work up a load for the 150 grn ELD-X and RL-19 powder. There isn't much published data on this combo. Will someone please run it through Quickload do I can have safe starting points and max load?
Thanks in advance for your help!
