So here is a tech tip, most all ranges and certainly any match requires a chamber flag. Now you can go to your local store and purchase one for sure. As an instructor often times I need several as students typically do not have one. So I fabricate my own. A piece of weed eater string with a wire nut on the end and you have a perfectly acceptable chamber flag for no cost. Keeps your local RSO happy! PS you want a thankless gig be an RSO!
