What are your results?
For me, 50 yards is practical. Zero at 50 gives relatively flat shooting between 30- and 160-yds (+/- 1 inch). This is for my red dot KS with 10.5-in barrel and 123g Wolf.
Here’s a chart for zeroing at 50 followed by zero at 25. If you know what your intended common range will be, pick the best for you. 25, 50, and 100 aren’t set in stone although they’re common:
Edit: The charts are based on 2350fps mv from 20-in barrel, so might have a little/lot of difference from 10.5-in barrel
