The problem isn’t the “rifleman” part of it. Women are frequently better shots than men. The problem is simply a question of strength and stamina, which, for most women, is less than for most men.
When I am out at the range I just sit down, take my time and squeeze off a round in good time. Now if someone was shooting back at me I suppose it would be much different. That’s when you would find out just what a good shot you were.
