From Wikipedia, the free encyclopedia:
"The 6.5-284 is a wildcat cartridge based on the .284 Winchester cartridge necked down to 6.5 mm. The .284 Winchester was created around 1963, but never really caught on, except as a parent case for the wildcat 6.5mm-284. The 6.5 caliber allowed for the use of long, aerodynamic bullets. In 1999, Norma submitted it to CIP. It has since been standardized as the 6.5mm-284 Norma.
It has been used extensively in benchrest competitions and is known as an extremely accurate long range round. Using an improved version of the 6.5/284, Rich DeSimone set a 1,000-yard (914.4 m) world record at 1.564". Rich DeSimone's 1,000-yard (914.4 m) record has been broken by Tom Sarver Sarver in 2007 using a .300 Hulk wildcat cartridge that is based on the .338 Lapua Magnum cartridge. In contrast, most hunting rifles do the same at 100 yards (91.4 m). A 140 gr (9.1 g) class bullet can be driven safely to 3,000 ft/s (910 m/s). Also, there are many popular hunting bullets for this caliber, making it a good hunting round as well. The primary drawback of this round is the short barrel life of about 1,500 rounds."
