Many years ago, I loaded 30-30s with 100 gr. half jacket plinkers and 110 SP jacketed bullets. Don't recall having any problem other than accuracy concern because of the free space between the bullet and the lands (OAL). Then again, the 30-30 isn't known for extreme accuracy anyway. I'm sure that I followed recommended load data using rifle powder. Hodgdon list several rifle powder loads for the 110 gr. bullet. http://data.hodgdon.com/cartridge_load.asp
However, unless I could find reliable load data, I would be very hesitant to use 10 gr. or less of Unique in the 30-30 case. Sounds like a SASS or Cowboy Action Load??? That is a very small amount of fast burning pistol powder in a relatively large rifle case. Aside from inconsistent burn, there is no way to foresee what other problems might surface considering the amount of air space left in the case.
JMHO. My recommendation is to use the 110 bullets ahead of recommended rifle powder. I'll check my Loading Manuals and let you know If I find anything.
One of my favorite 30-30 loads is the Sierra 125 gr. Flat Nosed Hollow Point ahead of 35 gr. of H4895 as shown in the Hodgdon chart for the 130 gr. SPR FP.
