Lee Bulge Buster Kit For Bulge-Free Brass. Lee Precision knows that bullet casings for ammunition like .40 S&W .380 ACP and .45 GAP are notorious for the "bulge" that swells out near their bottom which prevents them from being reloaded and resized by reloading dies constrained by a shell holder. That's why this Lee Precision reloading tool comes in handy since it completely removes the bulge allowing you to use your normal reloading equipment for these specialized casings. The Lee Bulge Buster Kit comes complete with a catch container a push through punch and extension sleeve and an instruction manual. Simply mount the reloading equipment to your press and start punching to de-bulge all your ammunition allowing you to re-use and reload even .41 AE ammunition. Win the battle of the bulge by equipping your press with the Lee Precision Bullet Casing Bulge Buster.
