RWS centerfire rifle cartridges in calibre 8x57 JRS

RWS centerfire rifle cartridges in calibre 8x57 JRS

The 8x57 JRS is a first-class cartridge for combination guns, in particular for double-barrelled rifles. When used in double rifles, it obtains a very rapid shot sequence, because the barrel is not seriously misaligned with the first shot. 

Since there already was an 8x57 IR, the next logical step was to also create a cartridge with rim for break-open rifles in addition to the 8x57 IS with the stronger 8 mm bullets. Well, the 8x57 IRS is the rimmed version of the rimless 8x57 IS. It was introduced in 1905 as well.

RWS Rifle Cartridge with HIT Bullet (lead-free, stable-mass)

8x57 JRS

This brand new RWS HIT bullet was developed as a lead-free alternative for hunters who prefer to use non-fragmenting rounds. Despite this new lead-free bullet’s quick response, the expanding segment retains a stable mass. This guarantees deep penetration and reliable exiting even at high impact velocities and/or greater target resistances - such as hits on bone. The bullet’s superior properties fully come into play when used on larger game.  

In contrast to a fragmentation round, the lead-free and stable-mass RWS HIT bullet releases its kinetic energy in the body of the target through 100 % non-fragmentation. As a consequence, you can get the most out of the game you take down.  

As with all RWS rifle cartridges, the new HIT round also combines the usual advantages associated with our brand: it’s reliably effective, precise, causes less wear and tear on the barrel and is cutting-edge in design. RWS HIT Matrix – our cutting-edge bullet design:  

RWS TC Tip (bullet tip with 2 hollow chambers)The innovative bullet tip from RWS HIT serves two important functions: Its streamlined shape gives it has an improved BC value and longer trajectory. That, in turn, means: higher bullet velocity and greater impact energy.The interaction between the two hollow chambers produces lightning fast expansion across the entire front-end of the bullet. That guarantees a high shock effect and ensures game is brought down on the spot.  

RWS ACC (hollow-point bullet design)The Active Crater Cavity (ACC) provides for optimum absorption of the initial deformation triggered by the TC tip, which acts to further accelerate the deformation process. This results in perfect, fragment-free expansion with predetermined spreading immediately upon impact.

RWS HIT at a glance:

  •  lead-free hunting ammunition
  •  avaiilable in calibre .300 Win., .30-06 and .308 Win
  • stable-mass deformation bullet
  • deep penetration and reliable exit wound
  • high imact velocities
  • best preservation of venison
  • cartridge for strong game
RWS HIT

Structure of the HIT bullet   

  1. RWS ACC (Active Crater Cavity) for actively accelerated mushrooming and high shock effect
  2. RWS TC tip (Twin Compression Tip): with 2 cavities for initial deformation and flat trajectory
  3. Nickel-plated, solid copper projectile with extremely high BC value
  4. Boat tail base for flexibility and in-flight stability
  5. Performance grooves for better delivery
