Grandpa-in-law and grandma-in-law (those are words right?) just received their CHL's in their upper 80's. Grandpa is legally blind, but scored 100%. He can see the green paper with a brown wall behind. He just aimed for the middle of the green and nailed it. Grandma had even better groupings. She's got much better vision. Obviously both then came away with perfect scores. Picture of grandpa attached. My family has had CHL's for years. Other in-laws already had CHL's. We are just waiting on my brother-in-law now to reach 100%. Anyone else from a gun family?
