Wish they were heavier - Champion Target Redfield Style Sight-In Targets

I've used various iterations of this target for 30+ years. They are straightforward and easy to use, with instructions printed on every target. Have used them for both rimgire and center-fire rifles. Over the years, the paper used to make them has become lighter and lighter. Not too much of a problem if you have a good rigid backstop on which to secure them.
