RWS centerfire rifle cartridges in calibre 10,3x68 Mag.

RWS centerfire rifle cartridges in calibre 10,3x68 Mag.

The consistency of properties found in the 10.3×68 Mag. and the blend of proven tradition with state-of-the-art technology open up entirely new opportunities. The large projectile profile, its variable weights and the jaw-dropping stopping power with a pleasant recoil behavior are what make this caliber unique.

The 10.3 projectile diameter also ticked all the boxes for cutting-edge hunting requirements when attached to the legendary 68 RWS case length. The underlying idea of the 10.3×68 Mag. was to design an extremely balanced and harmonious cartridge with a unique range of possible projectile weights between 11 g and 26 g by reducing the case length to 68 mm.

RWS Büchsenpatrone mit SPEED TIP PROFESSIONAL Geschoss

10,3x68 Mag.

The .338 Lapua Magnum long-range caliber is becoming increasingly popular. On the one hand, rapid technological advances in firearms and optics has made it possible to shoot and hunt at ever greater ranges. On the other hand, ammunition used on hunting trips has to be suitable for a variety of distances and game weights. High penetration and stopping power is indispensable, for instance, when hunting in mountains or for large African game.

RWS has now developed a hunting bullet for this high-velocity caliber that reliably covers distances ranging from close by to over 400m that can also handle a variety of game weights. The RWS SPEED TIP PROFESSIONAL is one of the latest developments from RWS meant to provide a very high shock/stopping effect even at long-range. The streamlined shape of the RWS SPEED TIP PROFESSIONAL projectile is topped off with a Speed Tip nose to assure reduced air resistance and thereby provide for an extremely flat trajectory. This novel bullet tip ensures accuracy and maximum instantaneous effect even at longer ranges. The bullet employs a V-tail, which also assures increased accuracy and stability in flight over long distances.

The SPEED TIP PROFESSIONAL was designed for a wide range of uses through its dual-core lead construction based on the proven H-shell principle that employs a slightly softer, rapidly fragmenting front core and a harder, fast penetrating tail core. The nickel-plated, mild carbon steel casing also ensures that the expanding segment of the projectile retains a high degree of form integrity so that it is able to produce a good exit wound and a clear blood trail even in larger game!

That's what makes the RWS SPEED TIP PROFESSIONAL the ideal design for this particular caliber in terms stopping power, penetrating effect and long-range effectiveness.  

Advantages at a glance:

  • High-velocity ballistics. Extremely flat trajectory together with very high velocity makes it possible to hunt at very long range. This is achieved through the projectile's long-range form, including in particular its Speed Tip and V-tail.  
  • Extreme knock-down power. Quick response in the body of game is achieved through the Speed Tip with its integrated hollow point and the quick-fragmenting front core. The harder tail core provides for guaranteed penetration power. When used in hunting, this results in significantly reduced game flight and good exit wounds with clear blood trails.  
  • High precision. Unmatched precision is a prerequisite for long-range hits. This is guaranteed by the precision V-Tail and the bullet's nickel-plated finish.
