I'm getting a green dot Holosun Vulcan optic. It's the first one I've ever had, and it was the one recommended by my peers for beginners to start with, coming from iron sights, especially with astigmatism and bad eyesite in general.
Regarding the optics and shooting in USPSA and NRA Action pistol events, what yardage should the optic be set at? It seems like most of the USPSA stages are set at 10-15 yards, but there are some that are farther 25+. Do I want to set it for the furthest distance I most likely be shooting at? How would I adjust my aim to accommodate the different distances?
Should I use my distance glasses for shooting the with the optic? (These are the ones I have for shooting clays). Or do I use my progressive glasses?
