First.

Yes, in general, you can use the jacked data for the cast bullet of the same weight but I don't recommend you use cast data for Jacketed.

Second.

Do not start anywhere near that load.
Since you do not mention the cartridge, I would not mention a charge weight but if you have only a max load, reduce it by at least 10% to start.
If you have a starting load and a maximum load, reduce the starting load by 5%.
