I use a VERY LARGE piece of Cardboard (That surrounded a new Chest Freezer) Hang a Target at the top of it, Take a Wild guess on Sight adjustment? Take aim and Let it Fly, in hopes that i hit it Somewhere? In this Case i did my First Shot, it was LOW, I made an Adjustment and Shot 2 more times, they were Good Then i pack the Gong up, in this Case the Wind Started in on me, and it KEPT GOING, Getting worse n Worse. I was happy to Hit the Steel ANYWHERE on this outing, It’s to much work to Set all of this Stuff up in the Mountains like i do and Not get to Shoot, But i have had to leave before without Firing a Single Shot. My next go around at this will be more for Accuracy on an Official Size Open Sight Target, and Sight Settings.
