VC, I don't see where you are losing any range or energy, I see it as an increase in both as well as trajectory. That is why you have a shorter "best sight in range", because the trajectory is flatter so there will be less hold under at shorter range and less hold over at longer ranges. Lets face it, without rifling in your barrel a rifled slug has about a 100 yard maximum before it starts to wobble.
There are other companies loading Brenneke Slugs such as Dynamint/Nobel Rottweil.
Here is some FAQ from Brenneke USA:

Question: Why do your slugs work with choked barrels? What do the ribs do?
Answer: In 1898 Wilhelm Brenneke invented the modern shotgun slug. The most revolutionary aspect of his invention were the ribs. They make it possible to shoot any of our lead slugs from any choked barrel, regardless of choke size. The ribs are compressed when they pass through the choke, and excess lead is squeezed into the gaps between the ribs. There is no danger to the shooter, to the gun or to bystanders, and no wear and tear on the gun. Excellent accuracy is retained. In 1992, we added minor improvements which resulted in even higher accuracy: five-shot groups of under 2" at 50 yards are possible. Depending upon the case length (2¾" or 3") you can effectively use our slugs up to 100 yard ranges. Note that our SuperSabot and our Super Magnum are designed only for use cylindrical full-rifled barrels, and must not be fired from any type of choked barrel.
Question: What happens if I shoot your slug in a rifled barrel?
Answer: All our slugs can be shot from rifled barrels. No problem at all. Normally you will achieve even higher precision from a rifled barrel than from a smoothbore barrel. Groups of under 4" at 100 yards are no problem from a rifled barrel with our normal slugs.
However, we have two specialists, slugs designed for use in rifled barrels only: our Super Magnum (Gold), a 13/8 oz slug and our SuperSabot, a 11/8 oz expanding (up to 1") brass slug. These two products provide maximum accuracy (under 2" groups at 100 yards) from a rifled barrel, at ranges of over 100 yards.
Question: Does a rifled choke tube enhance the accuracy of your slugs?
Answer: Yes. Better accuracy is obtained by using a rifled choke tube. Almost all of our slugs can be through these types of chokes.
Please note, however, that our SuperSabot and Super Magnum are designed for use in cylindrical full-rifled barrels only, and must not be fired from any type of choked barrel, including rifled choke tubes.
Question: Why do the ribs of the Super Magnum (Gold) turn to the left, while the twist in rifled barrels is to the right?
Answer: Because almost all rifled shotgun barrels have a right-hand twist, that is exactly why we gave the ribs on the Super Magnum (Gold) a left-hand twist. The Super Magnum (Gold) is designed for rifled barrels only, and the ribs have no effect on the rotation of the slug. Their purpose is to provide superior guidance within the barrel than a slug without ribs is capable of.
The left-turning ribs also provide a better grip on the rifling within the barrel, resulting in superior rotation of the slug as it exits the barrel. This was proven during extensive research performed when we developed the Super Magnum (Gold).
We actually found that left-twisted ribs on the slug result in much better transfer of the barrel's rotation to the slug than did right-twisted ribs. It may seem strange, but consider that most automobile tires have their "ribs" (profile) also against the driving direction, in order to provide maximum grip.
Q: On what maximum ranges do your slugs provide sufficient precision and knockdown power?
A:
Slug Maximum
Distance Game
SuperSabot 12 / 2¾” 80 + yd. big game
SuperSabot 12 / 3” 100 + yd. big game
K.O. Sabot 12 / 2¾” up to 80 yd. deer sized
K.O. Sabot 12 / 3” up to 100 yd. deer sized
Super Magnum (Gold) 12 / 3” 100+ yd. large / dangerous
Black Magic Magnum
12 / 3” up to 100 yd. large / dangerous
Magnum 20 / 3” up to 80 yd. deer sized
Magnum .410 / 3” up to 35 yd. small / varmints
K.O. 12 / 2¾” up to 60 yd. deer sized
Heavy Field Short Mag.
12 / 2¾” up to 100 yd. deer sized
Low recoil 12 / 2¾” up to 35 yd. deer sized
Buckshot 12 / 2¾” up to 25 yd. deer sized
Question: Which of your slugs are suitable for self defense/police work?
Answer: Primarily our slugs were designed for hunting purposes. However, law enforcement officers in Germany soon found out, that they are very helpful in duty applications. We have two rounds that are very suitable for police work/self defense:
Low Recoil 12 GA: 2¾" case with a 1 oz slug. With 1511 ft lbs, more than enough stopping power, but due to the low recoil loading quick follow-up shots are possible.
Buckshot 12 GA: 2¾" case with 9 pellets (hard due to 6 % antimony, also copper plated), weight 11/8 oz.
Question: What is the velocity, energy and drop at various distances, and the optimum distance for sighting the rifle in on your slugs? Answer: Please refer to the data given on each product page sheet or on our homepage (
www.brennekeusa.com). If you hunt at shorter distances only, please contact info@brenneke.de, and we will provide you with individual data.
Question: Don't the left-hand ribs on the Super Magnum (Gold) make the slug turn to the left against the right hand twist it gets from the barrel after leaving the muzzle?
Answer: A slug rotating one way that is forced by the air to rotate the other way will be unstable and unprecise. But first, in order to set a slug into rotation by air, you need much more than these small ribs. You need something like a fin or a tail wing to get a bullet rotating. Oddly designs with extended ribs or screw like slug heads are just cosmetic, as they have practically no influence on the rotation of the slug. Second, the Super Magnum (Gold) slug is rotating at 50,000 rpm. Wind resistance on the ribs is negligible.
Therefore, you do not have any negative effect caused by the ribs outside the barrel on a clockwise rotating slug, as the superb accuracy of less then 2" at 100 yard proves.
Question: What benefits do the CleanSpeed coating provide?
Answer: When a lead slug passes through a shotgun barrel, a substantial amount of lead residue is left behind. This makes cleaning a barrel tedious and a lot of work. Not with CleanSpeed! The special CleanSpeed coating acts as a lubricant, reducing lead fouling in the barrel to almost zero.
Question: What is the difference between Original BRENNEKE® and Rottweil BRENNEKE® other brands with BRENNEKE® slugs?
Answer: BRENNEKE® has worked as a subcontractor for other great ammunition companies for over a century. We delivered our slugs, they loaded and sold them. Therefore, you will find BRENNEKE® slugs with almost every leading shotgun cartridge manufacturer. Companies like Dynamit Nobel/RWS and other European manufacturers use our slugs, because they are simply the best.
In 1995 we decided, in order to serve the U.S. customer better, to load our slugs and sell the cartridges directly through distributors/dealers in the U.S. Our newest slugs, like the SuperSabot or the K.O. Sabot that provide state of the art in accuracy and knock down power, are available only through BRENNEKE® USA.
So, if you are looking for an outstanding shotgun slug, buy the original. Buy Original BRENNEKE® slug cartridges.
