I don't know anything about frangible bullets, but powder only cares about how much weight is in front of it. And, of course, the hardness of the jacket material.
So, if the jacket material is no harder than conventional jacketed bullets, 110-grain data oughta work.
I guess.
You can always start with a medium charge of slow-burning pistol powder. For example, I've long used 20 grains of 2400 as a plinker load with 169-grain lead gas-checks. Works okay with stray/leftover 150-grain jacketed bullets.
