I suspect that many folks who have marksman ship problems with this range, twenty-five yards, are challenged by seven yards.
Why do you so suspect?
Personally, while seven yard drills were standard in old LEO shooting practice, I seriously doubt that that is a very realistic distance for lawful defensive shooting.
Take the time it takes to draw and fire one shot. On average, that means that a defender will not
draw much before an attacker with a contact weapon is at a distance he can run in a second and a half, or a little more.
Say, twenty-one to twenty-five
feet.
Much farther, and the lawful justification for drawing will likely be much in question.
Even an attacker armed with a handgun is unlikely to start shooting at twenty-five yards, or even seven. He is more likely to conduct an ambush from around a car or gas pump--close range--to surprise, and to try to successfully obtain cash or keys or a car.
The question, then, is about the distance at which the defender will
start shooting.
Might not seven
feet be much more reasonable? Or anywhere between five and ten?
At that distance, with the attacker moving at around five meters per second, the challenge is not really one of "marksmanship".
The challenge is to shoot the attacker as many times as it takes, in perhaps one second or a little more at best, while moving off-line.
Bullseye groups are not the objective--they would indicate that the defender iis shooting
far too slowly.
