R I F L E C A R T R I D G E S QUALITY IS DECISIVE CUSTOMIZED PROJECTILES Compromises are not allowed when it comes to the quality of ammunition. The shooter‘s safety takes top priority in both development and production. Although all regulations contained in the weapons code are binding on every producer of ammuni- tion, certain quality differences are clearly apparent in practice. This applies particularly to cheap brands, where it is only logical that some areas are sub- ject to big savings. RWS, on the other hand, resolutely fol- lows the high-grade route here, from the original idea in the development of a product right to the inal visual inspection in Quality Assur- ance. All components, from the ignition cap over the case and propellant right to the projectile, pass through a perma- nently monitored production process. Perfectly matched to each other, the components are then assembled/illed and subjected to a series of strictly speciied quality inspection procedures. More than 100 production steps are required before a car- tridge is released for delivery. RWS is the world‘s only major producer of rile cartridges who offers bullets for hunting purposes of its own manufacture exclusively. More than nine different hunting projectiles and numerous other types for military, police, industrial and sports applications are available, which no doubt makes RWS the supplier with the widest spectrum of projectiles altogether. Latest production methods guarantee highest dimensional accuracy and impeccable surface characteristics. The jacket is drawn and cut to length several times, and one or two lead cores are pressed in, depending on the type of bullet. Grooves and other features are produced to suit the speciic projectile. A last dimensional and visual inspection follows after the pro- jectile is calibrated. Random samples are taken daily from each production lot to check the precision. The projectiles are loaded into to cartridges and thoroughly tested from different test barrels. The spe- cialist weapon trade is supplied with nothing but bullets, which have satisied the strict RWS-internal speci- ications. The above are the most important ones of the many process steps necessary to create the special RWS projectiles. We have been masters at these procedures for generations. Nothing enjoys a higher priority with us than your success when you are out hunting. What are the particular characteristics of rws projectiles? • Outstanding precision • Optimally stretched trajectory • Energy output in the body adapted to the weight of the game • Readiness for deformation appropriate to the iring distance • Short escape distances IT‘S THE PERFECT MIXTURE THAT MAKES THE DIFFERENCE Cup 1st draw 2nd draw Cutting Prepressing Head pressing Necking and perforating Turning of rim and length How do we achieve the high quality level of our RWS cases? After the bands are punched this starts already with the dra- wing of the cups. RWS cases are drawn in three stages, anne- aled after each draw, pickled, rinsed and subjected to further measures increasing the quality. The effect is a speciic course in the hardness of the brass case and an increased resistance to exceptional strains. After the irst cutting operation the cases are pressed, the mouth of the case is annealed once more; the case is pickled, rinsed and saponiied. Next, the case mouth and shoulder are necked, the ignition channel is perforated, the rim is turned and the case cut to length again. Annealing of the case mouth takes place once more before the case undergoes a 100% dimensional and visual inspec- tion. Random samples are taken from each lot before produc- tion progresses. These samples are assembled/illed to com- plete cartridges and subjected to extreme excess strains: All assembly stages from the insertion of the ignition cap over the lacquering of the ring gap, illing of the propellant, placing of the projectile right to the adjustment of the cartridge length and crimping of the bullet are accompa- nied by electronic as well as visual inspections. Detailed testing of the chambering ability (by gauge) and auto- matic weighing of each cartridge prior to packing complete these inspections. • at 10% excess pressure in especially prepared test barrels with partly inadmissible head spaces of 0.2 mm and 0.4 mm. These head spaces are to simulate worn weapons, which exist on the market. • At 30% excess pressure in test barrels produced to CIP spe- ciications. Here we have developed a test programme, which extends far beyond what is required by the law. Even competitors describe this procedure as a merciless testing method, which reliably reveals possible existing nonconformities in the propellant case. Rile cartridge cases must withstand most extreme gas pressu- res of up to 7,000 bar. It is not for nothing that experts refer to them as the shooter‘s life insurance. We have developed this probably most demanding test of the industry to ensure that you are always on the safe side. A case, which passes our quality inspection, is of a special format, it is an RWS! Anvil-type ignition Nitrocellulose powder Projectile Case Gelatine is the ballistic target medium, which comes nearest to the density ratio of muscular tissue. This makes the material perfectly suit- able for developing and testing projectiles, so that scientists can optimally simulate the effect in the body of the animal. The test irings provide information on the energy transfer behaviour of a bullet. The course of the tear length permits to draw exact conclusions on the energy output in the body. After iring the block of gelatine is sliced and the tear lengths visible in the form of rays are evaluated. A curve results, from which the transfer of energy into the body can be deduced. On the next pages you will see the results of the different special RWS projec- tiles (.30 calibre) ired at blocks of gelatine. Firing onto the gelatine block 2 3 “Impressive performance, 91% to 97% resid- ual bullet weight, perfect for hunting at normal and long distances” from „Patronen im Test“, Asmo Talvikunnas and Henrik Olbert, DWJ, 12/2005 PENETRATES DEEPLY Evolution bullet Simulated wound channel in gelatine block .30-06 EVO 11,9 g .308 Win. EVO 11,9 g “A very precise projectile for all middle Euro- pean game with a special adequacy for game weighing from 50 kg upwards (dressed carcass). Most probably also a perfect choice for driven hunts for wildboar and deer, with plenty of power for all sizes of game, delivering a suf- icient blood trail… The precision produced from all guns in use (Merkel-Bergstutzen, Blaser R 93 Varmint, Blaser BBF 95) is outstanding… Exit holes were consistent, even with diagonal shots at game over 50 kg (dressed carcass) … The big- enough exit holes dependably yielded ample blood” Frank Heil, Journalist for leading hunting magazines THE SPECIAL QUALITIES AT A GLANCE: • Impressive penetration – even with bone hits! • Wenison preservation – almost 100% residual weight due to power bonding • Excellent precision • Barrel protection • Flexible application options • The deformation process is quick and reliably initiated by the new Rapid-X-Tip ® • IMPRESSIVE PENETRATION – EVEN WITH BONE HITS! The advantage in effect of the Evolution ® bullet is very impressive with shots hitting bone, especially in heavier game: Upon contact with the game body, the deformation process is reliably initiated by the new Rapid-X-Tip ® . The Evolution ® bullet emits enough energy at the entry side to trigger the required shock effect. Classic softpoint bullets frag- ment when hitting stronger bones and therefore have less residual energy for penetration and exit- ing. The Evolution ® bullet remains essentially mass stable. This ensures that the required penetration is achieved even after bone contact and provides a high chance of a clean exit (see graphic below). • EXCELLENT PRECISION The Evolution ® bullet is characterised by its good ballistic precision. This is a result of its many new features including the friction reducing nickel plating of the cartridge jacket and the ballistically optimised calotte of the bullet. The aerodynamic geometry of the Evolution ® allows a longer tra- jectory and ensures higher shock energy even at longer distances. • BARREL PROTECTION Many hunting cartridges cause high transverse stress in the barrel due to their rigid jacket con- struction. This is not a problem with the new Evo- lution ® bullet thanks to the design of the lexible calotte. The bullet’s smooth nickel cover reduces deposits in the barrel to a minimum. • VENISON PRESERVATION – ALMOST 100% RESIDUAL WEIGHT DUE TO POWER BONDING With the Evolution ® bullet fragmentation is reduced to a minimum. By special bonding of the lead core with the Tombak jacket (Power Bonding), the Evolution ® cartridge achieves a residual weight of nearly 100% and therefore ensures impressive venison preservation. • FLEXIBLE APPLICATION OPTIONS Due to its unique construction the Evolution ® bullet delivers consistent deformation at all shoot- ing distances and on all types of game. Its extraor- dinary penetration is extremely effective on larger and heavier game. .30-06 EVO 11,9 g .300 Win. Mag. EVO 11,9 g “Out of 5 roebucks shot at the heart 4 went straight down and just one buck ran about 20 m. Exit holes showed a diameter of 2 to 3 times the caliber.

The HMK behaves exactly in the way intended by its design, as a partially bursting Simulated wound channel in gelatine block projectile. The tip bursts quickly by releasing frag- Tombac jacket ments, while the rest acts as a stable penetrating The twin-core projectile consists of two lead cores of different hardness and a jacket of tombac. For the separation from the softer tip core, the harder tail core is provided with an additional tough tombac jacket. The weight ratio of the cores is 50:50. A tail groove located in the rear section of the projectile reliably bonds the tail core to the outer jacket. A second groove in the front section forms the sharp rim (hair at location of impact) and is at the same time the predetermined break- ing point for the front jacket of the bullet. This is an important aspect for the tearing-off of the other- wise hindering bullet lares. The design results in a straight shot channel, which causes the important bullet exit hole. THE SPECIAL QUALITIES AT A GLANCE: • Good and safe reaction of the game to the shot • Extremely short escape distances • The sharp rim resulting from the design guaran- tees the desired hair at the location of impact • Optimal energy transfer in the irst half of the body • A reliable bullet exit hole guarantees suficient blood • Only minor devaluation of the venison cylinder.

Harder tail core “In line with the underlying philosophy, the front part of the projectile bursts while releasing the Residual body of projectile appropriate fragments. The rear part remains intact as a penetrator. Good shooting reports on red deer ACTS QUICKLY H-jacket bullet (H-Mantel) are to hand.” From “68 rile projectiles and how they act in the animal‘s body” Simulated wound channel in gelatine block (Hunt & Nature, issue 5/1999) Hollow tip of copper 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 frag- ments and transfers much energy. The cylindrical tail part separates at the H-groove, penetrates the body even if bones of strong animals are hit, and provides the desired exit hole. THE SPECIAL QUALITIES AT A GLANCE: • Limited fragmentation due to the H-shaped con- striction • The tail part is slightly deformed upset in its diam- eter and thus provides an exit hole reliably • The venison is destroyed to a minor degree only • Quick death of the animal from shock “...Approx. 75 % of the shot animals lay at the location of hit or within a minimal distance Tip core after a short death light. Even at greater iring distances the projectile provided the desired effect H-shaped constriction with deformation and separation of the front part of the bullet.

In summer I choose the ID Classic for roe- bucks and also for the foxes. Where we live we Simulated wound channel in gelatine block get an ever increasing number of sows and with The basic idea of the ID Classic is to ideally com- bine the „width and depth effect“ in the target. This was achieved by uniting two lead cores of dif- ferent hardness: the soft front part in the shape of a plug reaches into the rear, hard and heavier part. This “marriage of lead” is enclosed by a jacket of soft steel, which becomes gradually thicker towards the rear. The torpedo tail with its bigger base area (by one third) improves the external- ballistic behaviour thanks to higher light stability. The rear core of the ID Classic projectile is more laid out for readiness to mushroom and energy transfer in the body of the animal, which makes the bullet particularly suitable for cloven-hoofed game of light to medium weight. THE SPECIAL QUALITIES AT A GLANCE: • The sharp rim punches a distinct, circular bullet entry hole and provides the desired hair at the location of the impact • The front core bursts and releases fragments to a limited degree • The harder rear core with its funnel-shaped recess mushrooms and as a rule provides the sought bullet exit hole • The necked tail limits the tearing off of the jacket lares • IDEAL for hunting light to medium-sized game my repeater I succeeded already several times in bagging more than one young wild boar from the Softer tip core Nickel-plated steel jacket horde. At these game weights the ID Classic of Sharp rim calibre 7x64 bans the shot animal on the spot. There is always a bullet exit hole and if the young Harder tail core Tail constriction boar happens to go a few metres into any thicket I ind suficient blood even by the eye.“ Torpedo shaped tail Residual body of projectile Hans Heinlein, hunter and farmer EXTRA HARD UNI Classic bullet „...I have been using the UNI Classic bullet in calibre .30-06 Springield in my 98 for years, Simulated wound channel in gelatine block with growing enthusiasm. What I particularly like The UNI Classic bullet was developed as a comple- tion to the ID-Classic - especially suitable for hunt- ing medium to big game. The harder and heavier tail core of the UNI Clas- sic reaches with its tip into the soft part at the front. As a result the projectile tends somewhat less to mushroom, while its penetration force is increased. The torpedo shaped tail with its bigger base area (by one third) improves the external-ballistic behaviour thanks to higher light stability. THE SPECIAL QUALITIES AT A GLANCE: • The sharp rim punches a distinct, circular bullet entry hole and provides the desired hair at the location of the impact • The front core bursts and releases fragments to a limited degree • The harder rear core tends to retain its shape and reliably provides the desired bullet exit hole • The venison is destroyed to a minor extent only • UNIVERSALLY applicable for hunting heavy game up to dangerous game about it is the very good effect on red deer and wild Softer tip core Nickel-plated steel jacket boars. This is especially evident also when lead- Sharp rim ing guests to strong stags, in the repeat or inishing Tail constriction Harder and heavier tail core shot. The shot game reacts clearly.
