You can rough it in with dove loads at 10 yards. The problem is that the dove loads don’t hold together well enough for me to tell where it’s at anywhere past 20 yards. I rough it in at 10-20 with dove loads and then do my final adjustment at 40. Generally from what I’ve seen, if you rough it in at 20 with doves loads, the tss will be a little low at 40 yards.
