Must Reading The next edition of SHOT Business magazine is in the mail, and if you're not signed up for your free copy, you'll miss articles on the new in-line guns and how to sell black powder, the oldest firearms technology. You'll read interesting observations about customers who bear watching and others who deserve a second look, plus get the latest on old clothes -- actually, the longest surviving manufacturer of clothing apparel for hunting. Subscriptions are free to those in the retail firearms trade. Visit the Web site at http://www.shotbusiness.org to qualify.
