Cast boolits loads for 300 whisper

I am building a 300 Whisper on a 722 Remington action to use as a cast bullet shooter. I should have it in a week. I have the reform die ,223 cases and plenty of 30 cal cast booltis of different sizes.

Problem is what loads do I use. I have Red Dot, Unique, 700x, H322, 4895,Varget and H2227.

Can I get some loads out these powders that will give 1600fps plus or minus?

Thanks much and Happy Thanksgiving.
