The Lee 2nd has some good data (up to 267 grn cast) for 44spl, that I used w/ my long gone 4" 624.
Also, Brian Pearce has a very good write up on 44spl loads (3 different pressure levels), in Handloader No. 236, August 2005. Probably still available, & worth the $10+/- if you shoot .44SPL.
I think that 300 grainers are a bit heavy for that caliber, but as long as they are not cast too hard, you can probably make 800+fps pretty easy, w/ mid range powders. Unique, PowerPistol, VV N-330, or N-340, all being good choices. VV N-330 (Lee 2nd) always worked better then Unique, for me.
Just start low, & work up. You will probably find your sweet spot before you encounter pressure issues. Even if you DON'T make 850fps, I'll bet you end up w/ a great, one ragged hole, stop 'em in their tracks load.
