Sumo Sight ICFRA plots sheets and other downloads.

Here are some ICFRA plot sheets that I made.  They work well for me, hopefully they are some use to you.  Understand that there is a fair amount of inaccuracy on any short range target if you are not exactly at the designed distance.

Here is my 308, 155gr fullbore zero range target.  Fairly accurate elevation based on a Sumo 30mm fixed height sight.

This is the Excel spreadsheet I use to determine recommended fullbore ring sizes on ICFRA targets.  It also seems very accurate for me.  Adjust as needed.  Send me comments on it's accuracy please.
