Anyone loading 150s in the 7 SAUM or 280 AI with '26?

Does reloader 26 actually exist? I have been looking for some for 150's in my 270 win, and cant find any in my neck of the woods.

Or mine.........

aceman2101,

Where are you in Montana? I've purchased all of mine from stores in Helena and Big Timber. In fact I was in the Helena store last week and they had some, but I didn't buy it since have enough for a while.

In my limited experience RL26 works better with heavy bullets in a given caliber. I loaded some Hornady 154 Interlocks for my 280AI and didn't get any better velocity or accuracy than using H4831. My buddies 280AI cut with the same reamer shot 160's and 175 bullets much better and had good velocity using RL26.

Berger data showed 26 as giving highest velocity with a 140 in the 6.5 Creedmoor.

That's what I'm thinking but I believe I'll give it a tray anyway.

Aceman201, I gave up and ordered some R26 from Grafs, If you order enough powder then the Hazmat fee is a wash compared to local GS prices per lb.. At least it is here.

What kind of speeds are you looking for? I'm shooting 160 grain Accubonds in my 7 SAUM with a 22" barrel. Magpro(half a grain below book max) gives me 2930fps. IMR4350(at book max) gives me around 2850fps. RL22 is right there with these powders, velocity, wise. Accuracy is great with all of these powders.

It is a LITTLE bit faster than RL25. My data shows 1-2 grains LESS than RL25

Thanks. Do you mean 1-2 grains less than R25 to get the same velocity with 150s in the 7 SAUM?

I'd like to get at least 3,000 with the 150 Scenars. I can get excellent accuracy and 3050+ with IMR 7977 (23" bbl) but there's no "book" data and the load appears a little hot.

That speed with the 150's seems doable. I can push a 168 Berger at 2950 using 60.5 grs of RL26

Just seeing RL-26 for 140s in the 260... Did I miss it?


RL26, 6.5 Creedmoor, 2977 with the 135 Classic Hunter... G7 .303. That oughta work.

I worked up some 26 loads for 150 grain BT's in my AI. Had good results, but it didn't beat out my rifle's preferred load using RL-19. Worked jam up for me with my 270 and 150 grain NF's though.

Boomer: I did not look at the 135...interesting!

Picked up a pound of R26 yesterday

Fotis: Thanks! I owe you one.

R26 is great in the 280AI and the 6.5x55. Be very cautious with quickload data the BA is for R25 which is too slow for 06 size and smaller cases. I would feed in the Alliant 270 data and see if that changes the BA.

My rifle the charges ended up about the same or one more grain than the R22 loads. With 140s in the 280 AI I ran up to 66grains with no pressure signs but dropped back a grain or 2 depending on bullet for around 3200 fps.

BA?

RL26 worked good in my 257 Roberts with bullets heavier
than 110gr. Works good in 270 Winchester with bullets
140gr or more. 7MM Mag I only shoot 160gr Accubonds about
the same as Norma MRP,Retumbo,and the RL26. RL23 worked
best in my 257 Roberts. You may be able to get more FPS
from the RL26 in you push it than I have.

Muledeer, I live in Missoula. Sportsman Warehouse, Bob Wards, Cabelas, Selway Armory, nothing. I may just order some on line and pay the hazmat fee

graf's had it a couple days ago. Probably still do

I'm interested in RE26 max loads with 6mm (100+ grain), 25-06 (115 grain), 7mm RM (175 grain), and 300 WM (200-220 grain).

Check the Alliant site click on R26 and all loads. Info on 243 which will get you started on the 6mm. The 25-06, 7RM and 300 have listed loads so you may carefully extrapolate that info for the bullets your using.

In my experience stay closer to R22 data than R25 if no tested loads exist. But in the 270 WSM R26 was almost the same as R25 in charge weight. I am not sure if this holds true with other magnum sized cases or not.

Re: the thread title - would those be for things like sprinkles on Christmas cookies?

A powder-related variable in QuickLOAD one can adjust when the predictions are off.

A veritable fudge factor, eh?

Yes, but not the only one. ;-)

aceman2101, there is a guy here in Billings selling an 8 pound keg for $120. If you want me to try to get it, let me know. I will be meeting a friend from Missoula the weekend of the 5th and 6th and could have him take it to Missoula with him.

I,m still working with RL26 in all 3 calibers, but right
now several other powders are more accurate. Such as Norma
MRP in the 7MM mag, and the 270 Winchester. Several other
powders work just as well in the 257 Roberts, such as
RL22, Norma MRP, RL23, and RL17.
