Actually, apple pie filling is probably more dense than water, so a 1 cup measuring cup full (8 oz by volume) will weigh almost (9 oz). Like you said, minus the container.
I don't think it really matters though, the more apples the better for me!
The only reason I know this is because when I make soap, the measurements have to be much more exact and I have to weigh everything. Weights and volume measures aren't always the same.
