Interesting fact: Word Champion in women’s 10 metre air pistol (Santo Domingo 1981) — Kalinina Nonna — aimed on the center of the bull’s eye (center hold).
Kalinina Nonna — Word Champion 1981, European Champion 1975, four times USSR Champion 1973-1977.
Rarity… but possible.
I have tried center hold yesterday in air pistol. Not so hard. I shot my usual scores.
