RWS centerfire rifle cartridges in calibre 8x57 JS

RWS centerfire rifle cartridges in calibre 8x57 JS

The 8x57 JS is a first-class cartridge for distances up to about 180 m. It is ideal for hunting in the woods and as cartridge for drive hunting. It is also a first-class large game cartridge for Central European game. It is readily used as a universal cartridge there. As a rule, there is less haematoma formation than with rapid smaller calibres

The 8x57 JS was developed from the old military cartridge 8x57 J by increasing the bullet diameter from .318 to .323" (8.08 / 8.20 mm), and an "S" was added to the designation. It was introduced in 1905 and the hunters soon appreciated it.

RWS centerfire rifle cartridge with ID Classic-bullet

Bullet RWS ID Classic
8x57 JS

The essential thought of the ID Classic inventor was to ideally combine "width and depth effects" in the target. This was achieved by bonding two different hard lead cores: The front soft part protrudes like a plug into the rear harder and heavier part. This lead "marriage" is enclosed by a jacket of mild steel which gradually thickens towards the rear. The torpedo tail, with a third larger base area, improves external ballistic behaviour with its higher flight stability.

Construction ID Classic-bullet

 

  1. Harder tail-core for convincing penetration 
  2. Sharp edge for cutting of hair at point of impact 
  3. Softer tip-core for controlled fragmentation and high effectiveness 
  4. Nickel-plated steel jacket for increased barrel life
  5. Tail constriction for a mass-stable residual body and a sure bullet exit
  6. Torpedo-shaped tail for high flight stability

Mode of action

Shot on a block of gelatine with a length of 35 cm. Shot distance: 100 Meters. Caliber: .30-06

  1. Energy transfer on lightweight game (at 10 cm): 1.535 J
  2. Energy transfer on heavyweight game (at 15 cm): 2.320 J
  3. Total energy transfer: 3.097 J
  4. Maximum energy: 195 at 7,5 cm
