Starline hylsa .270 Winchester

Introduced in 1925 along with the Winchester Model 54 bolt action rifle under the name "270 WCF" (270 Winchester Centerfire), the .270 Winchester was not an immediate success due to the popularity of the relatively recently introduced .30-06 Springfield, chambered for the M1903 Springfield bolt action rifle, which was commonly "sporterized" for hunting purposes.

However, the .270 Winchester attained great popularity among hunters and sporting rifle enthusiasts in the succeeding decades and especially in the post-World War II period, ranking it among the most popular and widely used big game hunting cartridges worldwide, especially with the widespread popularity of rifle scopes. Shooters started noticing that the .277" caliber cartridge was capable of shooting flatter than the popular 30–06.
