NRA 2014: Dupleks 12-Gauge Shotgun Ammunition – Effective R.I.P.?

Dupleks, a Latvian ammunition company was show-casing their environmentally friends (and what looks to be highly effective) steel ammunition. They have multiple options including a similar segmenting slug design to the recently reviewed G2 R.I.P.

Up first are two all-steel slugs designed for hunting in the dense woods typical of the eastern Europe. Dupleks claims that the steel slugs penetrate and pass through intervening materials that would ricochet or deflect lead rounds.




The Dupo is a expanding round… but let’s get to the Hexolit.  Designed along a similar vein to the maligned R.I.P. ammunition, the Hexolit is a (1.13 oz.) expanding and fragmenting steel slug. However, I would suspect the 12-gauge has more than enough energy to support the fragmenting round concept and still push the slug’s core to effective penetrating depths.




Rounding out the slug offerings are the SuperTarget Sport, a “match” shotgun slug for competition shooting (Note, in Latvia rifles are highly regulated, shotguns are much easier to access). The Kaviar is a frangible slug designed for practice or home-defense users worried about over penetration.



What do you think? Is this what the RIP desires to be or a failed concept?

    It looks like a well made fragmenting slug, but who/what are their “environmentally friends?” 😉

    • DiverEngrSL17K

      The “environmentally-friendly” bit is simply a reference to the fact that the D-Dupleks slugs are manufactured from steel rather than lead. It might not seem to make that much of a difference when one is looking at relatively small amounts when considering an individual’s usage, but it does add up considerably when one takes into account overall collective usage.

      • An Interested Person

        I know what he was trying to communicate, I am just poking fun at his grammar. “Environmentally friends” makes no sense at all, it should be “environmentally friendly.”

      steel slugs, no lead.

  • iksnilol

    Saw those long time ago, nasty stuff (the good kind of nasty).

    • DiverEngrSL17K

      You said it — works exceptionally well for a wide variety of tactical and hunting scenarios.

  • Tom

    I bought a box of Hexolit32 from Midway (back when they stocked it) for hunting and didn’t have any complaints. Dupleks stuff is a bit pricey and honestly you could down the same animal with a lesser priced slug/buckshot, I took the plunge and bought a box and so far as long as I’ve done my part it’s done its part and I’m satisfied. However will I buy another box to use again? More than likely not as I can’t justify the price when I can get the same (end) results with a cheaper slug.

    I can personally vouch for the effectiveness of D-Dupleks shotgun ammunition. They have been around for several years now and actually offer multiple variations of the Hexolit, Dupo, Monolit and Rossa lines of steel expanding and non-expanding slugs ( I won’t go into the numerous details — you can simply look up their products on-line at ) in 2-3/4″ ( 70mm ) and 3″ Magnum ( 76mm ) sizes. I have used these in a wide range of shotgun types ranging from a plain-jane single-shot break-open Rossi 12-gauge through a modified Mossberg 500 tactical pump-action shotgun to a VEPR-12 semi-automatic, and they have not failed to perform — reliable, accurate and powerful with outstanding penetration and on-target terminal effects, yet without harsh recoil characteristics in most types of shotguns, The sleeved steel slugs are also designed to work well in both smooth-bore and rifled barrels, and won’t foul your shotgun’s barrel the way lead slugs might. Technically, the plastic sleeves on the slugs can be considered as sabots in terms of function, except that they don’t strip away when the slug leaves the barrel. The other nice thing about the D-Dupleks slugs is that they are not subject to deviations in trajectory by intervening obstacles such as heavy brush and even small to medium-sized tree limbs, a Godsend in dense, close country.

    The downside? D-Dupleks ammunition is a good bit more expensive compared to the vast majority of the competition ( which almost universally specializes in lead alloy-based slugs ), and is more difficult to obtain in the U.S. since it appears to be imported in batches and therefore is either immediately available in large quantities or almost not at all at a given time. I personally feel that the benefits of the trade-offs are worth more than the added cost and frustration, while the fluctuations in supply can at least be partially offset by simply exercising a little patience and / or purchasing some extra ammunition when it is available. However, others might see things differently depending on their preferences and priorities.

    D-Dupleks also manufactures armor-piercing hardened steel shotgun slugs that have really impressive penetration against a variety of NATO-standard body armor and other “obstacles”, but these are available only to approved military and select LE end-users under strict rules.

    I love DDupleks ammo. I mostly shoot the monolit 32, accurate, reliable, hard hitting. I find they are relatively undamaged after passing through a steel automobile rim.

    The Hexolit is pretty nice to and on a hog it provided dead-right-there performance, though to be honest I have not found any 12 gauge slug that failed on hogs.

    Great ammo, neat article.

  • bbmg

    With the power of a 12 gauge cartridge behind it, this sort of projectile becomes something to be reckoned with. You need a lot of force to drive an irregularly shaped projectile through living tissue, so making a similar bullet for a 380 just isn’t going to cut it.

  • derfelcadarn

    Kaviar referred to as a shotgun shell. Energy mass and speed are all that is required here. How much do the steel parts weigh all else is secondary.

  • Pete in Alaska

    I’ve been using the DDupleks products for several years now and have blogged about them from time to time as well. As an Alaska bear round it is superior to anything else out there. I might also suggest that one should consider the AP-20 round in their line up as well. The AP-20 will stop a truck or car engine with one shot. I know this from personal experience. I would expect it to also make a very good, mid range, dangerous game round as well. Both the Monolite and Hexolite rounds have served me well. The Hexo round is a very heavy hitter indeed. These 12 gauge rounds have now traveled with me everywhere I travel. I back them up with #1 Buck loads and have found the combination as near perfect for a 12 ga as one can imagine. If its a defense shotgun round your looking for, DDupleks is THE provider you want! Period.

    • Rusty Shackleford

      The AP-20 sounds interesting yet nobody has any for sale. I wonder if the ATF considers something like the Serbu Super Shorty not just an AOW, but a pistol as well, just to get rid of 12 gauge AP ammo?

  • Sulaco

    Looking at their site it does not look like it can be ordered either….

    • DiverEngrSL17K

      If you are in the U.S., try — this is not a plug for any particular vendor, it’s just that they happen to have a large quantity available at the time of writing at reasonable prices, and have always had a good reputation as a reliable and responsive ammunition supplier.

  • Giolli Joker

    All that everyone has already said clears any doubt about the effectiveness of these non-gimmick rounds…
    I’d just add that the comparison with the G2 RIP isn’t right because these fragmenting slugs have a conventional mass (for their caliber) to guarantee penetration of the core and the fragments while the RIP rounds are lightweight bullets whit a mass that after fragmentation doesn’t leave enough residual energy.
    The G2 approach on a 12GA would still be effective, but a waste of the potential of the cartridge.
    Conversely the DDupleks approach on pistol calibers could be seen on the original Triton Quik-Shok, and the effectiveness of those (at least on ballistic gelatin) was way superior than the RIP.

  • Jon Abbott

    For Goodness Sake! Spell check your articles! Misspelling “gauge” undermines your credibility.

  • dilby

    I have never seen anything wreck ballistics gelatin quite like the DUPO28.

    See the gooey madness for yourself:

    • Rick

      of course, can we even get these shells anymore?

      • DiverEngrSL17K

        Rick ( and all the rest, too ) — Check out SG Ammo ( ) ; they have several hundred boxes of several types of D-Dupleks 12-gauge ammunition available at the time of writing at reasonable prices. Hope this helps a bit.

  • J.T.

    The first four have been on the market for years, they are nothing new. The last two I have never seen before.

  • matt

    Na, have always and will always use 000 buck shot. If I have to shoot some moron they wont get anything special cause they don’t disserve anything special.
