Home Forums Hunting & Shooting Ask The Gunwriters Temp. Sensitivity of R-26

Thanks Pharm (and everyone else too).

That target looks like what I've been getting with 68 grains of Re25 and the 162 ELD-X.

Have you run that bullet into flesh yet?

I'm at 3115 fps with the 108 ELD-M in the 6 Creed with 22" barrel. Shot it in several matches, and it's consistent.

I'm wondering if '26 is actually slower than '25, even though the number is larger. Seems to me '26 could be a tad faster in some applications.

Would like feed back on that.

It varies with case capacity. In most cases especially medium 06-08 size it is faster than 25. It loads close to R22 & MRP with usually 0.5 to 1.5% increase in charge weight.
In the 270 WSM R25 & 26 load the same but this is the only instance I have run across. Quickload has the burn rate factor too slow for R26 listing it as slower than R25. I have not used it in the large cases like the RUMs etc so may perform differently in them. It seems very constant in any temperature sensitivity but there might be a pressure spike above around 90-100 degrees. The actual case temperature could be higher if left in the sun or a hot vehicle. Have not checked this out thoroughly enough to tell yet.

Thanks for that info.

I like RL-26 enough to have picked up an 8# jug. That should last me for a while. It's pretty versatile for a slow burner, works well in a number of applications. QL has it as top producer in a bunch of rounds. It may not always be the most accurate.

I tried it in my .257R with 115's. It left unburned granules in the chamber, couldn't chamber the next round. After I got back to the shop, it was OK, rounds chambered. Guess the obstructing granule(s) bounced out with the 4 wheeler ride from range to house.

But, for larger cases, it seems to burn clean and with great performance.

Yep

Nice.

A few hundred pounds of good eating. Nice rack, too.

How'd you get him off that mtn.?

DF

Like this

Nice. That's pretty darn good velocity with said parameters.

Very nice bull. Congrats and thanks for the feedback!

Reminds me of the story, 300# out of shape hunter, huffing and puffing on a mtn hunt, turns to his guide and asks how that guide would get him back to camp if he had a heart attack or something. The guide with a matter of fact answer informed him that he had taken a thousand pound elk off that same mtn just last week. The hunter asked how he had done that. Guide informed him, ten trips...

This just in:

Alliant has no tested load data for the 6mm Creedmoor.
I will submit your request to the engineering lab for possible future development. But, there is no timetable as to when this may be looked at for development.

Semi-hijack, I suppose. Sorry.

There ya go. '26 on top, followed by 4000 and '23.

Seems the new powders rule.

DF

In useing Reloader 26 in the 6.5X55 swede with the 147 eld it showed no change in velocity from 70° down to 20° Here in a few months I will test down to zero. Not a 6.5 creedmoor but very similar in case capacity.

Currently I'm getting ready to work up a RL26 142 LR Accubond load to use this hunting season and also thinking about trying RL16 in place of 17 for my 130 accubond load.

What's you best '26 load, 147's in the Swede?

DF

I'm useing a Tikka T3 with a SWFA fixed 6 in Warne Rings Not lapped


At 49.5 gr of RL26 velocity is 2730 fps
Lapua Brass
Rem 9 1/2
Coal 2.200 at .010 off the lands. This seats the bullet with the bearing surface just above the base of the neck
Loaded to less than .001 run out necksized only with Lee collet on once fired brass


This load is so far proving to be wicked accurate and produced groups at 500 yds pushing the 1" mark on 4 different occasions with temps from 20° to 70° all groups shot on different days starting with a cold bore. I've only shot 7 groups at 500 to date and the other 3 groups were under 2". Seems pretty consistent though I still need to test at zero° This is the only load I've ever had that would push the 1" mark at 500 in any rifle and gave me my first ever under 1" group that pushed the .75" mark

I ran the load all the way to 51 gr and showed no pressure signs. I noticed RL26 seems to burn a bit dirty when I tried it with a 130 accubond and also with 140 hornady interlock. With the 147 eld however it proved to burn much cleaner



Best wishes to you this hunting season

Trystan

How many shots in the groups? That’s a fine shooting rifle!

Thanks for that info.

Agree with '26 burning clean with some pressure, dirty without.

I reported how dirty it was in my .257R with 115's, not the powder for that one, for sure.

But, with heavies in bigger cases, clean, consistent and accurate.

DF

Not to hijack this thread but does anyone have data for the 6.5 Creed with 140/147's and RL16 or RL26?

Quit hijackin' the thread!!! By the way, anyone got data for R-26 and 105's in the .243?
