A question for those in the know.......

Ok, so I bought Ross's Victorio Strainer and I've used it once for grapes.
Worked great. Today I roasted my 2 Jack-o-lantern pumpkins and now I wanna
puree them. I have the Victorio all set up and I've put some cooked pumpkin
through it and I'm noticing there's an awful lot of pulp going out with the
skins. I could do a much better job by hand (y'know, peel the skin off with
a knife and then run the flesh through the food processor).

So is this what I should expect? Or does it sound like I'm doing something
wrong?
