So I'm trying to decide how to zero a 16" gun with a troy rear sight and fixed fsb that I plan to shoot both 75gr tap and 55gr plinkers out of. Any advice on which to actually set the zero with and how it will effect shooting the other? I'm leaning toward zeroing with the 75gr loads and then just noting the difference with the 55gr.

If I play with the point blank software what should scope height be set to? Height from barrel to tip of sight on fsb? If so it looks like a 50 yard zero on both would be pretty useful but with the 75 gr load the bullet will not go as high above the poa and will fall more than 2 inches below the poa sooner than the 55 gr load.
