Energy...3221??????? You can not figure dorps bassed on energy.....we need velocity, bullet (which you gave), and zero distance. Enviornmemtal info would also help.
We also need to know your intendid use.
Now,...... Rem 150 gr Core Loc PSP...velocity 2890 (2781 foot pounds...where you got 3221 from is beond me) as per Sierra I6.
Now, 100 clicks is 25 moa.
With a 300 yard zero, you need 149 clicks (37.2 moa)
With a 100 yard zero, you need 164 clicks ( 41.1 moa).
Your only choice to hit anything at 1000 yards is to dial up all the way and hold over for the rest. Remaining energy will be around 360 foot pounds.
Or change your setup.....20 moa scope bases are a good start.
Now if you are just plinking rocks, paper, steel, ect....work hard and have fun.
If you plan on hunting with this setup, STAY THE HELL HOME!!!!
Just my opinion, of course.
