Home Forums Reloading Big Game Rifles New RL23, RL26 in the 6.5x55 & 270 Win

The Kernals are small and easy to meter.
Temps is the low 20s and a good stiff wind. Not an accuracy day.

You can put a lot of this slower powder in a x55 case and 270 case

Forbes 24B 24" barrel

In choosing loads I started with RL22 and RL25 data.

Shooting 140 Berger VLD's in the 6.5x55 and burning RL26 OAL 3.150

50.0 grains .... 2,794
51.0 grains .... 2,856
52.0 grains .... 2,914

No "classic" signs of pressure, easy extraction.

RL 23 and 140 Berger VLD's

I shot one load of 47.0 grains for an average of 2,750.


270 Winchester Rem 700 Ti 22" barrel

Burning RL26 and shooting 130 Berger VLD's OAL 3.330

I tested one load of 63.0 grains for an average of 2,980.
Low ES of 5 on this load.

I seated the Bergers, (which don't have much shank) out at the end of the neck of the 270 case. Not much to hold on to.


My RL 26 load and 150 LRAB's didn't read. I'll have to try them later again.

Thank you for the results!!

Interesting I would like to try RL26 in my 280 Ackley !

I could not make RL 25 work in my 264, I would like to try '26. I wonder when it will hit the shelves around here. H'mmm might be of some use in the 6-284 as well.

I think it would be ideal for the 280 Ackley. 160 grain and higher.

I also think it would world great in the 260 Remington shooting 140's.

RL-22 = RL-23, but temp stable + anti-copper fouling additive

RL-25 = RL-26, but temp stable + anti-copper fouling additive

At least that is what I've been told so loads & performance should be same/same; that would make '26 too slow to be optimum in a 270, especially with 130's.

3K shooting 150's is not slothful for a 270 Win, that's for sure.

I figured the 130's would be to light but gave it a go anyways to give me an idea of difference

http://www.alliantpowder.com/reload...ight=150&shellid=63&bulletid=181

Also, because RL26 is smaller you can put more in a case. RL26 should work better in certain cases. You get the slow powder benefit of lower pressures and possibly be able to put more in a case for faster speed.

I've use quite a bit of RL 25 in the 260 (once fired Lapua brass) with good results (2,790 mv).
Now that 26 is out I would expect/guessing to see another 50 fps. I'll test some out soon here to know.

I would think RL 23 in the 280 ai. RL 22 was the best in mine with 160s

No, it's not & is what I get with 150's & RL-22 in mine with 24" barrels; 2950-2975 in a 22" barrel.

Trying to get my hands on some of the Nosler LR Accubonds to try but I just cannot find any right now.

A .625 G1 BC at 3,000 FPS looks really good to me...........

MM

Shooting Nosler 150 LRAB's

My rifle likes RL26 and 62.0 for a low ES average of 3,020 mv.

Really likes it!

Lapua brass
Win primer

Tried 57.0 and 58.0 grains of RL23 for 2,970 top speed.

Edited to change to 57 and 58

Anyone know if Alliant is coming out with R-18 and R-20? That is, the temperature insensitive versions of R-17 and R-19.

I do not believe that Reloder 17 is as sensitive as some make it out to be...... I never had a problem , and the temps here vary 100 degrees or so from season to season.................

How close to the lands on bullet seating do the LRAB's like?

On the RL-23, did you mean 57 & 58 grains instead of 47 & 48?

MM

Yes I meant 57 and 58 grains.

OAL was 3.340

A bit more info from ATK listed here as to their difference from 22 and 25 posted Jan 1, 2015

Good stuff on the 6.5x55........I had that in mind for mine and was wondering.

God Bless

The RL-26 .270 load with the 150 partition sounds like something I'd like to try.

+1

Great info. Thanks for sharing. I use a ton of 22 and 25..

More load testing today with the newer powders including IMR 4451.


6.5x55
Lapua brass
Rem primer
COAL 3.180

Nosler 129 LRAB
IMR 4451 46.8
2,930 average, low ES
This load rocks for accuracy at .4
(I'm guessing that this would be a great powder in the 260 Rem.)

140 Berger VLD
RL 26 52.5
2,945
2,964

150 Nosler Partition
RL 26 63.0
Nosler brass

I bumped the COAL to 3.40 from 3.35

3,080
3,074
3,103
3,061

Accuracy was just under an inch with the cold bore shot.
3 shots were touching.
The Partition likes the slower powder more than the LRAB.

Absolutely no "classic" pressure signs, easy bolt lift, no marks on case head, primers looked good, ect.

I think I likey a lot.


This was a reply I received from Alliant Powder

"Reloder 26 falls between RL-25 and RL-33.
Reloder 23 falls between RL-22 and RL-25.
Keep in mind that burn rates are only relative. Even though you may have two powders that follow one another, they may have completely different burn rates and/or characteristics.

Damn you Bob...

Wondering if a case full of re26 in the 300 win mag might be awesome....might tread on the heals of a wby.
W/the smaller denser kernal capacity w/180 bullets might be in the 83-87 grain area?

Hmmm...RL-26 and 150 gr NP's at 3k in a .270 Wiinchester. How long a barrel is being used for your data SU-35?

Bump for bbl length in the 270.....

Read the OP's first post.


Then think about it.......

BACK TO SQUARE ONE ON THIS ONE!

I asked Alliant Powder this question in regards to RL 26 compared to RL 25, as I wanted to start testing powder in my 7mm Wby.




Alliants respons.....


What does this mean??

http://bulletin.accurateshooter.com/2015/01/new-advanced-alliant-powders-reloder-23-and-reloder-26/

Within the above link:

"Reloder 26 is definitely slower burning than Reloder 25, so there shouldn�t be any confusion there either.�

"Reloder 26 is definitely slower burning than Reloder 25, so there shouldn�t be any confusion there either.�"

Seems by the latest report, they, Alliant, has changed their minds.

I don't think they really know yet.

I'm going to hold off buying more till I know more about these powders.

I really wonder about alliant sometimes.....I think they still have in their advertising (and on the container label) that mr4000 is a spherical powder.....shazam....open a can and its a short cut kernal.

Any more testing done on the 150gr/RL26 combo? Hitting 3000 with it is sweet. I've got a new 270 and a pile of 150gr Fusions I'm thinking of putting some RL26 under.

Anybody know where a guy can get a hold of some RL-23 or 26? Their load data looks promising for 7mm wsm.
Thanks,
bludog

I bought some of both at Whittaker Guns outside of Owensboro, Kentucky a couple of weeks ago, but don't know if they still have any.

Whiptail, I've found RL 17 to be very temperature stable, at least in my application!! I do all of my load development on 90 degree F plus days, and did testing of rounds at -4 F (allowed rifle and ammo to reach ambient before test). According to my chrno(and my surprise), I actually gained 8fps at -4! memtb

I'd like to try R26 and 140 gr. AB out of my 24" barreled Sendero.

From what I have seen these new powders don't offer much more in performance compared to RL 17, I am getting 2980 in my 270 wsm with the 150 partition using 57 gr of Rl 17, it takes about ten more grains of RL 26 to gain another hundred fps. My load shoots groups under 3/4 inch, I talked to a tech at Alliant a few minutes ago and he said that the main advantage with RL 23 and 26 is the reduction in copper fouling

Interesting, I have a couple pounds each of 23 and 26, will have to give them a whirl.

I've been pleased with the Speed & accuracy of the 270 with R22 under 130's.

If you can push 150's up to 3100 that's even better.

You skipped powders in your testing...

Try some '23.

I've shot up about 3# a piece of 23 and 26.

22 is done for me. I'll take 23.

I've got data for the 270wsm, 7wsm, 300wsm, and 300 Dakota.

Some speeds with my guns:

7wsm 26/150 LRAB = 3,200
270wsm 23/130NAB = 3,350
300Dakota 26/150tsx = 3,600
7wsm 23/120tsx = 3,450

All of these speeds were measured at 50 degrees F and showed NO pressure in my guns.

Based on Alliants data it would take about five grains more to get another 30 or 40 fps. Also based on their data a 270 win is only 66 fps behind the 270 wsm, the wsm should be out running the standard 270 by a wide margin, when using RL 17 the difference in speed in much greater.

Given what SU35 reported I'm really wanting to put RL26 under some 150s in my 270, but I haven't seen it in these parts yet. Ugg.

I've been looking locally for some RL26 to try for the past few months with no luck. Would like to try this powder in my 300 RUM and for another Kimber Montana 7 WSM that I'm about to have put together.

ewc
What are you loads in the 7mm WSM? Powder weight, accuracy & barrel length.
I shoot a 7WSM and have been looking for some to try. It looks amazing according to Alliant web site. Have you had a chance to try imr 7977 in the 7
WSM? I think this might be a good powder too.

62.0 grains of RL 26 will just physically fit into my new 270 Win Nosler brass. The book max load of 61.8 is into the case neck. That long sleek LRAB is a good powder compressor.

41rem,

Do you have any velocities or accuracy to report with that load?

Marked I found some RL 26 !

Does anyone know if 26 is temperature sensitive in the swede with the 140 berger?


Thanks
