The 6.5 x 284 is one of the premium long range cartridges. In 1963 the .284 was introduced as a magnum type cartidge with a rebated rim. It was designed to fit in short actions. The round never really caught on. It became very popular with wildcatters. In 1993 Norma necked it down to the 6.5 x .284. The 6.5 x .284 has been the named cartridge for the United States F-Class Team. Unfortunately, the large case volume results in short barrel life. This caliber begs for a Snap Cap. Dry firing is very important to barrel life in the 6.5 x .284. With the advent of 7mm Very Low Drag bullets, the .284 has seen new interest. The Harbour Arms Precision Snap Cap also fits the standard .284 and the .284 Shehane! Two Precision Snap Caps per Package.
