In the early 1940's Joyce Hornady and Vernon Speer teamed up to make bullet jackets from spent brass to help the war effort. After World War II Hornady bought the no longer used ammunition loading equipment from the US Government and started making ammunition for the civilian market. Today Hornady is one of the most innovative and trusted ammunition companies. With innovations like the Critical Defense line and the V-Max bullet Hornady is a easy choice for all your ammunition needs. The ergonomic Lock-N-Load Quick Change Hand Tool features a dual-sided chuck that allows for quick changeover of popular case preparation tools like chamfer, deburr, primer pocket reamers and cleaners, brushes or other tools with 8-32 threads.
