Monolit 28

Fast and accurate slug for long distance shooting. The slug body is made of steel and has a galvanized coating against corrosion. The recoil is short and soft, allowing fast aiming for the next accurate shot. It is especially suitable for semi-automatic shotguns. The slug is highly resistant against ricocheting and has an excellent capability to cut through various obstacles such as tree branches, bushes and dense grass. When shooting through obstacles - the slug retains initial trajectory well. On hitting the target, the slug ensures powerful impact. It does not disintegrate during the hit and therefore does not contaminate the meat product. The modified Monolit 28 Sport slug with a reduced propellant load can be quite effectively used in sports shooting.

Monolit 32

A powerful slug of the Monolit series with a 32 g weight provides high accuracy results in areas extremely densely overgrown with bushes and grass, where rifled weapon use is ineffective. At the moment of hit, Monolit 32 bullet provides especially strong impact. The flat frontal surface ensures complete impact energy transfer to the target. The slug body is lathe-machined, enclosed in a polymer casing and centered ideally, thus being very accurate. Slugs do not contain lead and do not foul barrels with lead foil and burned waste.

Dupo 28

A slug with a fast and powerful stopping effect. During the first moments of hit, it expands to a maximum diameter of 3 cm and provides strong impact within the whole expansion area. Meanwhile, the slug causes a powerful hydrodynamic shockwave on vital organs – respiratory, circulatory and neural systems. The internal hydrodynamic blow is the strongest effect of Dupo 28 slugs. Increased initial velocity allows using these slugs in driven hunting for shooting fast-moving targets without an especially large forward lead. The straight flight path allows long-distance slug shooting without vertical correction. Dupo 28 is a highly accurate slug ensuring fast and effective impact energy transfer, and an additional hydrodynamic shockwave inside the animal body.

Rossa 32

This slug exhibits good accuracy in long distance shooting, thanks to a specially centered slug body. Good penetration capability combined with a large expansion effect makes this slug very suitable for big game hunting. The large slug entrance hole creates massive blood tracks, even in case of a bad hit. After hitting the body, the Rossa 32 slug performs powerful and deep penetration, usually remaining in one piece and not splintering apart.

Hexolit 32

A slug with an extremely enormous impact effect. When hitting the body, the frontal part of the slug instantly increases from 18.5 to 36-38 mm in diameter – this is the largest slug expansion diameter ever known. It creates an entrance hole with a 3.5 cm diameter, hits powerfully with all its expansion area and disintegrates into six symmetric splinters. The splinter cone causes an extensive area of damage. The unified effect of a hydrodynamic shockwave inside the body, along with splinter damage, ensures an unique instant stopping effect with the Hexolit 32 slug, which provides good results even with imperfect hits.

Dupo 20

The Dupo 20 expanding slug – a sudden but expected improvement for the 20 gauge. A new version of D Dupleks lead free expanding slugs – the Dupo 20, is now available for caliber 20/70. As a next step in the development of D Dupleks expanding slug ammunition, the Dupo 20 combines the powerful characteristics of a steel expanding slug with light recoil, a lighter gun and other good traits of the 20/70.

Monolit 21

Increased penetration ability and self stabilizing design are the most popular characteristics of Monolit slugs and the Monolit 21 is not an exception. Monolit slugs are known as reliable ammunition for areas where occasional obstacles in the flight path of the projectile can deflect the bullets from the initial aiming direction and cause a failure to hit the target.

Dupo 7

A new member of the D Dupleks expanding slug family – the Dupo 7 expanding slug for caliber 410. Continuing the successful line of D Dupleks expanding slug ammunition we have developed an expanding slug that features the same good characteristics as D Dupleks expanding products in other calibers.

DUPO 7 Short Magnum

DUPO 7 Short Magnum – ideal ammo for home defense. Suitable for use in all Taurus Judge revolvers. Most powerful 410 round designed for HD purposes with Taurus Judge.


Sport ammunition ST-20 for sport shooting and training. Excellent accuracy for smoothbore barrels.

Product design

The D Dupleks products have a unique design which serves as a cornerstone of their enormous efficiency. Slug material – steel – allows designing them as never seen before, resulting in superior efficiency compared to conventional lead slugs, as well as effects which are distinctive only to slugs made by D Dupleks.


The steel slugs made by D Dupleks differ radically from traditional lead slugs used for a long time. As a non-conventional material for ammunition making, steel has provided the possibility to shape the slugs in the way most favorable to their flight characteristics and expansive effect. As a result, those slugs have uncommon characteristics, unquestionably superior than those of traditional lead slugs.


Various tests of D Dupleks products clearly show the strong points and advantages of each product. Test video materials allow viewing some finer details, otherwise unnoticed.
