.275 Rigby
or
Lee Speed in a .303
A great cartridge with a wonderful rifle . Would I prefer a 6.5 Creedmore ? I don’t think so .The Mannlicher Schoenauer was introduced in 1900, chambered for the rimless 6.5X54.
All model M1903 MS were chambered for it, as were the Y1903 military models and variants.
Mannlichers from 1891 had used the rimmed 6.5X53 (6.5X53.5mmR) which, other than the rim, is identical to the rimless 6.5X54MS. That cartridge has long been referred to as '.256 Mannlicher'.
The 6.5X54 MS uses a .264 projectile through a barrel with .256 lands.
