I agree, to the extent that I built a 4' x 4' grease plate to do so.

All I will say is that shooting a patterning plate with your guns is eye opening. Some will be more open than you thought, and some will be tighter. Some will "cross shoot" at certain distances, some will be perfectly regulated. Some will shoot higher, or lower, than you thought they did.

But, at least you will know.
