ICORE/revolvers/Ruger .357 Magnum Bill Drill Posted on September 13, 2013 by Caleb Sometimes, after a long practice session, you just need to do a bill drill for no reason at all. And it turned out to be a 2.33 with 6 hits on a 10 inch circle. Fun and useful! Share this:FacebookTwitterMoreLinkedInEmailPrintTumblrPinterestRedditLike this:Like Loading...
