I shot a .44 mag with a 2" inch barrel and a hair trigger.
At about 40 feet, the first shot hit the black. I couldn't hit the target with the other 5.
Some experts recommend a .22 for women because it's more important to get a number of shots in the kill zone. I't would probably be a good caliber for a man if he could get past his ego.
Another statistic suggests that a high degree of accuracy is not needed because most shootings occur within 20 feet or less.
