That load will get a PF of about 163. How much do you you need? 170? Wrong powder.
That load fills the case and is absolute max by my experience.
I suggest 10.5 gr of N105, for about 1400 fps.
They are called "bullets", not "heads", by the way. The head of the cartridge is other other end, where the writing is. It is called a "headstamp" because it is stamped on the "head" of the case.
