Here is a current photo of my back. I am pretty happy with my back/bicep progression. Still need to grow some wings, and I have just started implementing serious Power Shrugs in my upper days to build some mountains!

***Both Photos reflect my weight of 171 lbs at a height of 5'11***

I am trying to hit 180 lbs at maybe 12% bodyfat, I would assume at such a level I would have a faint outline of top 4 abs. I understand how to calculate macros for getting to 180 lbs, but how do you go about calculating macros for a bf percentage at a specific weight? Or is that simply not possible, eat for 180 and see what my composition looks like when I arrive?
