New Alliant Reloder TS 15.5 Powder — Outstanding Test Results

Alliant powder Reloder Reloader 15.5 TS TS15.5 Temp Stable extruded new Varget replacement

Outstanding New Powder from Alliant — Reloder TS 15.5
New Product Review by DasherDude
Alliant has devloped a new temperature-stable powder for long range applications. According to Alliant, this is a “slower burning version of the popular RL 15 with TZ technology” and brings some significant advantages over RL 15 and powders in the similar burn rate range (like Varget). The powder is named “Reloder TS 15.5″ (RL TS 15.5) and is created using the same TZ technology used in Reloder 16 (RL 16) and Reloder 23 (RL 23) whereby it manipulates the response of the propellant and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures. That makes RL TS 15.5 extremely stable across the full temperature range a shooter may encounter.

When Can You Get This New Alliant RL TS 15.5 Powder?
Alliant tells us that new RL TS 15.5 should start arriving on dealer’s shelves by the end of the month. Officially: “We will be putting it into distribution probably in April 2021 sometime”. Remember you heard about this powder here first.

The burn rate of RL TS 15.5 lies between RL 15 and RL 16 making it ideal for loading heavier bullets in .308 Win, 6.5 Creedmoor, 6mm Creedmoor, .223 Rem, and 6mm wildcats such as the 6mm Dasher or 6 BRA (BR Ackley). Being a bit slower than RL 15, new TS 15.5 offers higher velocities for the same charge weight as well as ability to load heavier charges for additional velocity without generating excessive pressure.

Testing Reloder TS 15.5 in 6 Dasher and .308 Winchester

I got a chance to test a pre-production powder sample of RL TS15.5 from Alliant. In my own tests with my 6mm Dasher and .308 Win, I extensively compared it with Varget that I normally use in these cartridges. In both cases, the results were nothing short of spectacular.

Powder Characteristics and Metering
This is an extruded powder and looks and feels similar to RL 16. The kernels are about 0.03 – 0.04 grains each (with the resolution of A&D FX 120i scale). RL TS 15.5 meters very well, although I had to slightly adjust the AutoTrickler to get it to meter perfectly.

As I found, later in the testing, that the powder compresses before it can generate excessive pressure in the Dasher, a drop tube helps to fill the case more efficiently if higher charges and velocities are desired.

6mm Dasher Test Rifle and Load
For testing I used my 6mm Dasher benchrest match rifle. This has a BAT 3L action, 28″ Krieger barrel, and McMillan stock. I use Lapua brass with CCI 450 primers to propel Berger 105gr Hybrids and this combination shoots quite well.

Load Testing and Velocities

Test in 6mm Dasher — Excellent Velocity, Low ES/SD
The testing comprised of shooting groups at 100 yards with increasing powder charges (OCW method) and then selecting a node. That node was found at 33.4 grains. The accuracy was excellent with remarkably low Extreme Spread and Standard Deviation (ES/SD)

My usual load is 32.9 grains of Hodgdon Varget which runs 2925 fps with an ES of around 12 fps and SD around 5 fps. For comparison, 32.9 grains of RL TS 15.5 delivered a velocity of 3022 fps. That is 97 fps greater than Varget for the same load weight (of RL TS15.5).

When used in the 6 Dasher, RL TS 15.5 had ES of 13 for 28 Shots — Remarkable!

More Velocity Plus Consistent ES/SD
Alliant powder Reloder Reloader 15.5 TS TS15.5 Temp Stable extruded new Varget replacementWith the Dasher since the new node (the sweet spot) was found at 33.4 grains, that resulted in a velocity of 3050 fps (a 125 fps velocity increase) from the same rifle setup. Not only did the velocity increase, but the SD was lowered to 3.6 with an ES of 13 (calculated over 28 shots). You read that right… 13 fps ES over 28 shots!

At 34 grains without any drop tube, the load was compressed. However, there were no pressure signs. That indicates that the 6 Dasher cartridge can be loaded with a higher charge, if a drop tube was used.

.308 Winchester Velocity Results
Similar results (velocity gains) were obtained from my .308 Win with Berger 200.20X bullets. For the same charge of 44.2 grains, I recorded about 100 fps higher velocity with RL TS 15.5, compared to Varget.

Accuracy Results at 100 and 300 Yards — Very Impressive

How does RL TS 15.5 shoot on paper? Very well indeed.

6mm Dasher Load Testing with Various RL TS 15.5 Charge Weights
The groups on paper told similar stories. For the OCW method, I shot groups of increasing charges at 100 yards and then selected 33.4 grains as the optimum charge (incidentally, it was one ragged hole).

While testing at 300 yards, the conditions were very windy but since I was testing for vertical, the point of aim was kept the same for every shot. No attempt was made to correct for wind, so the groups spread horizontally (15 mph, 3 o’clock wind) but the vertical spread of all the groups was under 0.3 MOA. That gives me great hopes for the long-range capabilities of the powder.

Thoughts and Conclusions

For the past year, Alliant powders have been a welcome surprise for this tester and they have found a home in my reloading room. I struggled to find a load for my .284 Win with H4831sc and H4350 before trying out Reloder 16 and voila, it was perfect.

I have used Hodgdon Varget powder for a long time in both my 6mm Dasher and my .308 Winchester. With the .308 Win I’ve used various bullets from 168 to 200 grains. Varget has served me well. I do always need to keep the powder charge in check and so the velocities are held back a bit. Now RL TS 15.5 looks like a very impressive competitor to Varget.

With Reloder TS 15.5, Alliant seems to have delivered a harmonious mix of great accuracy, higher velocities, and lower SDs without creating excessive pressure. All of this is delivered with a very temperature-stable package. The higher velocities may allow some shooters to hit a new, better-performing node. These qualities are highly sought after by long range shooters. Accordingly, I have no qualms in saying that Alliant has created a winner here.

Alliant Official Load Data for Reloder TS 15.5

New Products Featured in Shooting Industry Magazine

Shooting Industry January product showcase 2016

You can see scores of new-for-2016 products in the free January digital edition of Shooting Industry magazine. The new product offerings are found in a 28-page feature article starting on page 76 and ending on page 104. In those pages you’ll find new items from leading companies such as: Alliant, Browning, Hodgdon, Hornady, Lyman, Nikon, Ruger, Vortex, and Weaver Optics.

Important New Products
You can also see the new products in Shooting Industry magazine’s regular website, on the New Product Showcase Page. As a teaser, here are three new products from that page — new Alliant Reloder 16 powder, a new Bench-top primer tool from Lee, and a handy Lyman maintenance mat. We are VERY interested in new Reloder 16 propellant. Alliant says RL16 has a burn rate similar to H4350/IMR4350, which would make RL16 ideal for many popular match cartridges.

NEW Product — Alliant Reloder 16 Powder

Alliant Reloder 16 Powder

Alliant Powder Reloder 16 is a propellant that performs consistently across temperature extremes. Its burn rate is slightly faster than Reloder 17’s — well within the 4350 burn speed band. This makes it ideal for traditional hunting cartridges as the .30-06 and .270 Win. It will work as well with 6.5mm target loads and tactical applications where temperature stability is required. The Alliant Powder Reloder 16 contains a de-coppering additive but no toxic DNT or DBP.

NEW Product — Lee Auto Bench Prime

Lee Precision Auto Bench Prime Priming Tool

The new Auto Bench Prime from Lee Precision is an easy-to-use bench-mounted priming tool with a large lever that provides good “feel” with plenty of mechanical advantage. The symmetrical design allows for right- or left-hand operation. The Auto Bench Prime includes priming assemblies for large and small primers and a folding tray with a built-in primer-flipping feature. This allows direct filling from large primer boxes. The unit uses special, but inexpensive priming tool shell holders.

NEW Product — Lyman Maintenance Mat

Lee Precision Auto Bench Prime Priming Tool

The new Essential Rifle Maintenance Mat from Lyman Products is a smart item that any gun-owner can use. This 10″ x 36″ cleaning/assembly mat features small compartments for tools, parts, and cleaning item. The mat’s firm yet cushioned synthetic rubber surface protects your firearms. The Mainteance Mat’s molded-in compartments keep small parts and screws handy, yet out of the way. The Lyman mat is chemically resistant and cleans up easily.

New AR-Comp Powder Starts Shipping This Week

AR-Comp Alliant PowderAlliant is introducing a new extruded powder, AR-Comp. AR-Comp is an advanced re-formulation of Reloder 15, a double-base Bofors powder. There are changes to internal and external chemistry to provide much better pressure/velocity stability across a wide range of temperatures. The main difference between AR-Comp and Reloder 15, is the AR-Comp has a slightly faster burn rate, and AR-Comp is much LESS Sensitive to temperature changes. AR-Comp is a small-kernel, double-base extruded powder like Reloder 15, so it will continue to meter just like Reloder 15. The load density should be the same as Reloder 15.

AR-Comp should be at Grafs.com in a Couple Weeks
Here’s the good news — Alliant will start shipping AR-Comp to Grafs.com later this week. Dick Quesenberry, Alliant Powder Product Manager, told us: “I just received the AR-Comp packaging labels and we hope to send off the first shipments to Grafs this week.” With transit time, expect the powder to be available from Grafs.com by the second week of June. You can go ahead and place advance orders for 1-lb and 8-lb containers of AR-Comp on the Grafs.com website.

AR-Comp Offers Uniform Velocities over a Wide Temp Range
Tests were done with .223 Rem and .308 Win ammo, loaded with AR-Comp and maintained at temps from -20° F to +160° F in a controlled test center. The ammo itself was heated or cooled to targeted temps before testing. Across that entire range of temperature, -20° F to +160° F, the ammo loaded with AR-Comp showed a variation of only 20 fps in muzzle velocity. The primary bullet type tested was a 77gr .224 bullet and the secondary was a 175gr .308 bullet.

Burn Rate Like Varget
Though this is a reformulation of Reloder 15, the burn rate of AR-Comp is slightly faster than Reloder 15. Alliant told us: “Reloder 15 is slightly slower, in burn rate, than Varget. The new AR-Comp, with the enhancements, ended up slightly faster than Reloder 15, so it is now very close to Varget in burn rate”. This is the result of the “tuning” of the powder to be much less temp-sensitive.

AR-Comp First in Series of New Alliant Temp-Stable Powders
AR-Comp will be the first in a series of “new generation” temp-stable powders from Alliant. Quesenberry noted: “Our goal was to provide a powder that offers stable pressures in all temperatures. Shooters want to be able to stay with the same load in winter and in summer, in cold or in hot conditions.” Quesenberry added: “We’ve been working on this quite a while. AR-Comp is the first example and we hope to extend this to other rifle powders. It’s a tough job. You have to balance the performance carefully. We worked very hard to do just that and we think shooters will be impressed with the results.”

Reloder 15 Will Stay in Production
Fans of Alliant’s Reloder 15 don’t need to worry. Alliant will keep Reloder 15 in production. “We don’t drop powder lines”, said Quesenberry.
