Each Wednesday, the U.S. Army Marksmanship Unit publishes a reloading how-to article on the USAMU Facebook page. Yesterday's Handloading Hump Day post covered preparation of once-fired 5.56x45mm brass. This article, the first in a 3-part series, has many useful tips. If you shoot a rifle chambered in .223 Rem or 5.56x45mm, this article is worth reading.
