6.5-284 Norma

The 6.5-284 Norma originated as a wildcat cartridge based on the .284 Winchester cartridge necked down to 6.5 mm.

History
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.

Use
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 1000 yd world record at 1.564 in. Rich DeSimone's 1000 yd record has been broken by Tom 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 yd to 200 yd. A 140 gr class bullet can be driven safely to 3000 ft/s. Also, there are many popular hunting bullets for this caliber, making it a good hunting round as well.
