Point of Impact
Shooters may use a “point of aim” sight picture at 25
yards (See Figure 50-1). This means that, at 25 yards, the
bullet should impact the target at the point visible at
the top of the front sight. Springfield, Inc. firearms are
regulated to shoot point of aim, point of impact. Changing
brand or type of ammunition may alter point of impact as
well as shooter's technique.
I took the above off of page 34 in the owners manual. It also illustrates the sight picture. I was wondering if this was the point of aim you were utilizing. It seems at 3" high at 10 yards you may have been using the middle of the front sight dot as your point of impact instead of the top of the front sight. Doesn't make sense though that you'd be that low at 7. Maybe I'm wrong, but thought I'd ask.
