Reloder 23 and Reloder 26 — Good for Magnum Cartridges

Alliant Bofors Nitrochemie Reloader Reloading RL Reloder powder 22 23 25 26

Do you shoot a magnum cartridge? Here are two modern-formulation powders you may want to try: Reloder 23 and 26. We have been particularly impressed with Reloder 23. It has worked well in competition for target cartridges such as the 7mm RSAUM. Reloder 23 is like a slower version of Reloder 16 — a very temp-stable powder which has proven a worthy rival to H4350.

Ever heard of Alliant Reloder 23? Or Reloder 26? These two relatively new European-produced Reloder propellants were introduced in 2014. Most folks haven’t tried these Reloder powders because it took quite a while for the first shipments of RL 23 and RL 26 to arrive in the USA. But now these two new propellants are available in the USA, with substantial inventories in stock at some larger vendors. For example, Powder Valley has both RL 23 and RL 26 in stock now at $23.50 per pound. Many other vendors have ample RL 23, but RL 26 is a bit harder to find.

From our Forum members who shoot large magnum cartridge types with heavy bullets, we have heard good things about both RL 23 and RL 26. Reports from the field indicate that both these powders are delivering impressive velocities with low velocity ES/SD.

What are the characteristics of RL 23 and RL 26? That question was answered by Paul Furrier who works for ATK, the parent company of Alliant Powders. Posting in our Shooters’ Forum, Paul writes:

“Let me provide some factual info about these products. Some of the stuff that gets propagated is not correct. Reloder 23 is produced by our Swedish partner Bofors, and Reloder 26 is produced in Switzerland by our extremely capable partner Nitrochemie. I have seen it stated that they are both made by Bofors, so that is incorrect.

I have also noticed people are equating Reloder 23 to Reloder 22, and Reloder 26 to Reloder 25. Both of those statements are definitely incorrect. We do state that the performance of Reloder 23 is similar to Reloder 22, and it is, in general burn speed terms, but they are most certainly not the same. We have worked quite a lot of recipes for Reloder 23, and they are not the same as Reloder 22. Reloder 26 is definitely slower burning than Reloder 25, so there shouldn’t be any confusion there either.”

Furrier says that RL 23 is NOT sensitive to temperature shifts: “Reloder 23 was developed to bring a truly temp-stable powder to the Reloder 22 burn-speed range using Bofors new process technology. This is the second product developed for us with this TZ® process, the first being AR-Comp™. We see terrific efficiencies, SDs, accuracy and flat temp response from these powders. Please try them, I think you will be impressed.”

IMR Enduron 8133 — New Slow-Burn-Rate Magnum Powder

IMR Enduron Powders 8133 4955 4451 4166 7977

IMR, a Hodgdon Powder Company brand, will soon release a new, slow-burn-rate magnum powder, IMR Enduron® 8133. This new powder is designed for large, magnum cartridges, such as .300 Win Magnum, .300 Remington Ultra Magnum, and 28 Nosler, among others. With the slowest burn rate among Enduron powders, 8133 has burn properties similar to Hodgdon Retumbo. The new Enduron 8133 powder will be available in 1-lb and 8-lb canisters starting in February 2018. Load Data for this new powder is already listed on the Hodgdon Reloading Data Center.

IMR® Legendary Powders now offers five (5) Enduron powders: IMR 4166, IMR 4451, IMR 4955, IMR 7977, and IMR 8133. “It was always our intent to fill out the Enduron line with a magnum powder and we could not be happier with how 8133 performed in development and testing,” says Ron Reiber, Hodgdon ballistician. “This powder delivers the [slow burn rate] magnum-caliber reloaders require and adds all of the performance characteristics of the Enduron line of powders”. These qualities include temp stability, significantly reduced copper fouling, and optimal load density.

Modern Powder Technology for Enhanced Performance

Copper fouling reduction – these powders contain an additive that drastically reduces copper fouling in the gun barrel. Copper fouling should be minimal, allowing shooters to spend more time shooting and less time cleaning a rifle to retain accuracy.

Temperature change stability – the Enduron line is insensitive to temperature changes. Whether a rifle is sighted in during the heat of summer, hunted in a November snowstorm or hunting multiple locations with drastic temperature swings, point of impact with ammunition loaded with Enduron technology will be very consistent.

Optimal load density - Enduron powders provide optimal load density, assisting in maintaining low standard deviations in velocity and pressure, a key feature for top accuracy.

Environmentally friendly - Enduron technology is environmentally friendly, crafted using raw materials that are not harmful to the environment.

The Enduron Line-Up of Five Powders

IMR now offers FIVE Enduron powders that cover a broad range of burn rates. They are suitable for a wide variety of cartridges, from small varmint cartridges all the way up to the .338 Lapua Magnum.

IMR 4166 possesses the fastest burn rate in the Enduron lineup. It is the perfect burn speed for cartridges such as .308 Win, 7.62mm NATO, 22-250 Rem and 257 Roberts. A versatile, match-grade propellant, IMR 4166 is comparable to Hodgdon® Varget.

IMR 4451 is a mid-range burn speed powder, ideally suited for cartridges such as .270 Winchester, .30-06 and 300 Winchester Short Magnum. This powder is comparable to Hodgdon H4350.

IMR 4955 is a medium burn speed powder, falling in between IMR 4451 and IMR 7977 in burn speed. It provides top performance in big game cartridges such as 25-06, 280 Remington and 300 Winchester Magnum. This powder is comparable to Hodgdon H4831.

IMR 7977 has the second slowest burn rate among the Enduron Technology powders. It yields great performance in .300 Winchester Magnum, 7MM Remington Magnum, and .338 Lapua Magnum. IMR 7977 is comparable to Hodgdon H1000.

IMR 8133 is designed specifically for magnum calibers, such as .300 Remington Ultra Magnum, 28 Nosler, or the .264 Winchester Magnum, among many others. This new powder has the slowest burn rate among the Enduron powders and compares in burn rate to Hodgdon Retumbo.

Consider Alliant Reloder 26 for Magnum Cartridges

Reloder 26 Magnum cartridge Alliant RL26

We’ve told fans of Hodgdon H4350 to give Alliant Reloder 16 (RL16) a try. In our tests, Reloder 16 has proven a very promising rival to H4350 for accuracy, low ES/SD, and temp stability.

Now you can get the advantages of Reloder 16 in a slower powder formulated for magnum cartridges — Reloder 26 (RL26). Alliant says RL26’s burn speed falls between that of Reloder® 22 and Reloder® 33. That means it’s slower than H4831 but faster than powders that would suit the .338 Lapua Magnum. Reloder 26 has a high bulk density that allows larger powder charges, and high velocities. RL26 also provides a consistent, controlled response to temperature changes.

We are hearing very good things about RL26 from friends and Forum members who are testing it with big calibers for Long Range applications. Accuracy is good and velocities are impressive. Alliant says RL26 “incorporates EI® technology to produce extremely high velocities in magnum cartridges”. In big magnums, shooters have reported gaining 100+ fps with RL26 compared to H1000 or Retumbo. And to our surprise some guys have even tried replacing H4350 with RL26 (in smaller cartridge types) and they have picked up meaningful velocities. We don’t think Alliant ever intended RL26 as a substitute for H4350, but if you’ve got the case capacity… it may be worth a try.

Alliant Reloder 26 Features

  • EI® technology delivers high velocities in magnum cartridges
  • Contains proprietary de-coppering additive
  • Controlled temperature stability
  • Excellent lot-to-lot consistency
  • Formulation contains no DNT or DBP
  • Made in Switzerland for Alliant Powder

Alliant’s Tech Expert Talks about Reloder 26
What are the characteristics of Reloder 26? That question was answered recently by Paul Furrier who works for ATK, the parent company of Alliant Powders. Posting in our Shooters’ Forum, Paul writes:

“Reloder 26 is produced in Switzerland by our extremely capable partner Nitrochemie. I have seen it stated that they [it is] made by Bofors, so that is incorrect.

Speed and More Speed with RL 26
Think of Reloder 26 as a high-velocity powder for big cartridges. Furrier explains: “Reloder 26 is produced with Nitrochemie’s latest generation EI® process technology. This is the same impregnation coating process used to produce Reloder 17, Reloder 33, and Reloder 50 for us, and it is fantastic. Reloder 26 [offers] great ballistic efficiency, high bulk density so you can get more of the slow powder into the case to harness the energy, and decent, predictable extreme temp response. Reloder 26 is not as flat at temps as the TZ or Australian materials, but it is very manageable, usually in the 0.5 fps/°F range (depending on the application). Just as important, the pressure increases at hot are very manageable. We are using quite a bit of this RL26 powder in our Federal factory ammo due to the fantastic ballistics and accuracy.” — Paul Furrier, ATK
