I shoot H4350 in my 8 twist 26" barrelled 243 with 107smk.
I personally would try a faster powder for a 75gr bullet. Like varget, RL15, 4895, 4064.
No need for a mag primer unless it calls for it.

I am sure 4350 will work with a 75gr bullet, just not the most proficient way to push that bullet.
As for coal....try it at the bullet manufacturers suggestion
