Thanks! at what distance? does it matter?
This isn't a target.This is an old classic bullseye shooting tool that US Army Markmanship Instructors have used to help evaluate a student's one hand techniques.


If the bullet group in the student's target is located off center, the instructor can use this tool to indicate what the student is doing to cause it and suggest a fix in his technique.
My students shoot at a blank 11x14" piece of paper with a 2" black spot in the center from 7 yards.
For "new to firearms" students, twenty feet is far enough to show a good trend and still stay on paper.
