Pattern Board KISS Method ...

Aim at the black dot below the bottom Clay at 20 yards. If your core pattern is on the bottom Clay you are at 50/50. If your hot core pattern lands on the top Clay then your POI is 90/10 . You can Scotch Tape this 8x11 sheet of paper to your overall 3x3' pattern board paper to see the outer flyers and full pattern. All I need to see is what's on this 8x11" target paper for my records. You can do a Copy and Paste on your computer and print it out with my permisson.

This is a quick and easy way to do an amateur hit & run pattern test.

Give it a Shot,
