I shoot the small size paper plates. If you are missing those, you are shooting too fast. If you are consistently hitting center, you are shooting too slow.

I shoot the small size paper plates. If you are missing those, you are shooting too fast. If you are consistently hitting center, you are shooting too slow. 2-3x diameter of the paper plate is about center of mass for a person, so that 3x spread in shot during stress should still result in a hit.
