6.5mm/06
Introduced: 1913
Originator: Charles Newton
Other Names: 256/06
There is little difference between the 256 Newton and the 6.5mm/06, the latter being the wildcat version. The 6.5mm/06 achieved a degree of popularity in the immediate post-WWII era because of the influx of surplus 6.5mm military rifles. This case is easy to form and will work through any
standard-length bolt action with little or no alteration.
