Specifically for this bullet (Hornady #: 30196). Can't find load data for this bullet anywhere, not even in Hornady's load book. Point me in the right direction?
300blk Hornady 125gr fmjfb load data

Just pick any 125 load data and work up. Lilgun, H110 for fast loads, 4227 or 1680 will be slower. It's a handgun bullet, but will still work.

Are you sure that's safe given the different bullet types amax, sst, smk, etc? And if so could educate me as to why that is?

Hornady manual gives load data by bullet weight, not by individual bullets.

Most 125gr loads I see are for the Nosler boat tail, flat base tends to be a bit more forgiving and lower pressure than BTs, so probably OK to work up with that data. If you use a chrono you can use published vs measured velocities as an indicator of pressure for a given load. Depending on your powder of choice 300BO loads tend to be WAY below saami pressure max, so it's relatively safe to substitute the published bullet probided similar structure(not an all-copper HP with fmj data)

Seems a little iffy to me but to hell with it. Any load you would suggest to start with? The only reloading manual I have that includes 300blk is the Hornady.

I really like CFE black, good for supers and subs, really low pressures, even when compressed accurate and forgiving, but moderate velocities. calls for 19gr starting to -20gr-c max. In lil'gun 17.8gr-21gr-c, H110/296 is 15.7gr - 18.5gr -c, but max load is near it's 55k max saami pressure.
