RWS centerfire rifle cartridges in calibre .270 Win.

RWS centerfire rifle cartridges in calibre .270 Win.

The .270 Win. is a highly accurate cartridge that is extremely pleasant to shoot for light to medium-sized game, and thus best suited for roe deer, chamois and moufflon. Furthermore, it is a very good mountain cartridge with maximum effective ranges. The cartridge has only limited suitability for very large or dangerous game. 

The performance data of this cartridge from the year 1925, which is based on the .30-06 Springfield case, is very well balanced. 

A calibre widely used all over the world, particularly suitable for hunting deer, chamois, wild sheep and stags in mountainous regions.

RWS centerfire rifle cartridge with H-Mantel-bullet

Bullet RWS HMK
.270 Win.

Special about this bullet is its famous H-groove, a predetermined breaking point in the shape of a constriction in the middle of the jacket. It assists the separation of the two projectile cores and is, along with other factors, responsible for the bullet´s dual effective system: the front part bursts very quickly after the impact in the game, produces strong fragments and transfers much energy. The cylindrical tail part separates at the H-groove, penetrates the body even if bones of strong animal are hit, and provides the desired exit hole.

Construction H-Mantel-bullet

 

  1. Geometrically optimized tail for highest precision
  2. Hard tail core for extreme penetration
  3. Softer tip core for controlled fragmentation and high effectiveness
  4. Copper hollow tip for faster response in the game's body
  5. H-shaped constriction for reliable part fragmentation
  6. Modified cannelure for an optimal seat of the bullet
  7. Progressively increasing jacket wall thickness for a mass-stable residual body and a sure bullet exit
