No drop zone.

Some of the quarries around here are U shaped with the opening at your back. The most logical place for wind to come in at. I guess his must totally block the wind.

When all possible explanations are proven wrong, then the impossible must be so! http://www.youtube.com/watch?v=-b5aW08ivHU

Could be though. I've been to more than one quarry gun range and they were usually in quarrys that were dug into a ridge or simular formation so that they were more like box canyons....open at one end.

Wind protection could indicate lack of cross winds which is what most shooters are concerned with as they are hardest to deal with.

Shooting into the box with your back facing the open end you could still have a tailing wind giving the bullet more lift.

It was a large rectangle, closed at both ends. Only open side was up.

Only reasonable explaination.

It is, of all the stuff here that makes the onlyest sence,

Rifleman, at our age everything drops, or droops. :blah: Don't need gravity to help.

Maybe I am missing something but I generally hold low for uphill or downhill shots as you will shoot high when at an angle. It seems that this is what you are saying? http://www.chuckhawks.com/shooting_uphill.htm

:hmm: ......:idunno:

You know, I experienced the same thing shooting at a clubs range. In this case, the range sloped away down-hill. Once I stopped any kind of hold-over I was hitting the metal silouettes every time out to a little beyond 100yds.

Well, I read though all of the various answers and almost choked on all of the smoke :bull: that was being blown up your...uh....anal sphincter, and I agree with Apprenticebuilder that the most likely of the serious explanations is a difference in the lighting on your sights. The light could be changed by being reflected off the walls of the quarry. Now, I've got to get out of here before I choke on all of the smoke being blown. :haha:

I gotta disagree with the "trick light" theory, and support the slope theory. I'm betting if you took a transit out there you'd find a slope.

I have to disagree with your analysis as well, in the opening post the man said its flat.

If it takes a transit to locate a slope in 100 yds I really don't feel its enough to create the sighting error, also walking to and from the targets would reveal the change in elevation as well.

ApprenticeBuilder is right.

In order for a slope to affect trajectory it has to be significant enough to make the horizontal distance to target much shorter than the true distance.

Simply put, the incline or decline would be very noticable before it would move his point of impact that much at 100 yds.

Enjoy, J.D.

Well, if the light was tricky you'd never notice!! :rotf:

Sloop, light, whatever, it dropped.

Possible vacuum effect? Air moving across the top of the quarry creating a low pressure area within the quarry, effectively 'sucking' the ball upward, the same way an airbrush works?

Yeah, I know it's manure too, but at least mine sounds plausible! :blah:

Maybe not in the way you described, but it may in fact be due to a "vacuum". At least it sounds like someone is sucking air! :haha:

I still think there are demons involved. :shocked2:
