it usually hits around 40-45
I am much older than that I assure you!!!
I dropped down a medal at the World Police and Fire Games in Australia during the Palma matches because I didn't want to use my glasses for vanity reasons! With the front and rear apertures I didn't need them at reasonable ranges where I could still see the bullseye, but when I hit 800 and 900 yards I could not. I could see the target and guesstimated where the bull was ... silly me!
