I don't think the total paper count matters at all.

Count how many you had inside the turkey head (or kill zone.) Those are the ones that matter.

You can have 500 on a piece of paper but if 3 end up hitting what you were aiming at on the paper, then it means nothing.

If you don't have a turkey target, you can trace the outline of a coke can on a piece of paper. That's about the size of a turkey head. Shoot it. Count the pellets in the coke can. And that's what you want to know.
