8.3” PCC AR Pistol Zero Distance Question

Finally got my 8.3” HD pistol up and running and I’m going to the range this weekend to test out how well it takes JHP. I initially zeroed my Vortex Strikefire II to ~ 7yds. I have entertained the idea of pushing that zero out to ~50ft, and even with a 4MOA dot, I’m wondering what the sweet spot would be. What do you all usually zero your PCC pistols in similar barrel lengths?
