When you say reduce a pattern, you mean the shot pattern opens up with an overshot card under a fold crimp?

It depends on what you use for an overshot card. if it's tough enough to hold together it can disrupt the pattern and create a spreader load. Always best to pattern something like that so you know for sure what it's doing.
