Reloader 26 and the 270 Win

Has anyone played around with Reloader 26 in the .270 win? I want to run a 140 Accubond, but I can't find a starting point anywhere. Any thoughts would help.

Go to the Alliant web page. They have three loads for the .270, that will give you a good idea where to start.

I saw that for 150's not 140's though.

From another forum.

35 Whelen I tried some RL26 with a 140gr Hornady BTSP for the first time. I've been married to H4831sc for quite some time using the same bullet with great results. Just thought I would give this new powder a shot. I'm glad I did . I started at 58.5gr and worked up to 61.5gr.
58.5grRL26-2925
59.5grRL26-2955
60.5grRL26-3030
61.5grRL26-3115
Best group was 61.5gr at .5in. The others weren't as good. Primers were fine and bolt lift normal. I won't go any farther as that is more than good enough for me. At 3115fps this load tops my load using H4831sc by 200fps. That's considerable.

Reloder 26 and 140 and 145 gr in my 270 wins.

140 gr Nosler part from 24" barrel
59 gr 3020
60 gr 3073
61 gr 3124

145 Hornady ELDX from 25" barrel
59 gr 3072
59.5 gr 3095
60 gr 3119

Hope this helps. Accuracy has been a hit and a miss.

I've tried RL26 in both my 280 Rem, and 284 Win. While being fast, recoil was harsh. The tradeoff just wasn't worth it to me.
I do use RL26 in the 7mm Rem Mag.
It is excellent in the 243 Win with 100+ gr bullets.

I have been loading W785 in my 270 Win for several yrs. Shooting 140 gn Hornady BTSP and groups that could be covered with a quarter at 200 yds. The rifle hates 4350, 4831, 414, and 760 among a few others that I have tried. W785 was discontinued around 1983 and is listed 182 on a burn rate chart that I seen recently, Re25 is 180 on that chart. Question is will Re25 or Re26 work as well as the W785 did. I have not found Re26 on the burn chart and have found little info on it. With powder as hard to come by and prices more than doubled, just trying to find a good replacement for the W785

In my experience, Reloader 26 seems to do well when using heavy for caliber bullets in what ever cartridge you are loading for.
It's just too slow of a burn for most light bullets to build enough pressure to make it efficient.

Reloder 25 is just a hair faster than W785 on the burn chart I have. Re25 is listed 180 and W785 is 182. My rifle shoots 140 gn Hornady .277 BTSP by far better than any other bullet I tried. Techs at Alliant say they have no data for that bullet powder combination in 270 Win. So looking for some one that has. Only experience I have with Reloder powder is Re7 in 45-70

Reloader #26 will turn your .270 Winchester into a virtual mag cartridge. The data on my .270 Christensen is below.
Bullet: Nosler Accubond Long Range 150 gr.
Powder: Reloader 26 —59.4gr.
M.V.: 3027fps
S.D.: 5.1”
100yds - group .51

The .270Win and RL26 are magic.

Rifle: 700LA = 3.65 max COAL
27" SS 1:8 twist Preferred Barrel
0.290 freebore added
Light Palma contour

I will post up more.

I fell short on the ladders which is what I prefer to minimize bullet pulling. So here you go. I am a little curious to see how far the ladder will go so I will add a few more loads. But a 150 at 3137 is not shabby.

A friend of mine over in Cody, WY turned me on to RL 26 two years ago. It’s not only incredible M.V. for my 150 gr NALR, 3027 fps, but the groups are near mythical!
I was getting 3100+ with Alliant’s load data of 60.5 gr., but lost my accuracy—59.4 gr solved that problem. I just wished I could find more powder somewhere. My 8 lbs is going fast.

I used RL26 in my 30-06 for a great super fast and accurate elk load with 180 NABs. Everything was great loading it up in the 50s-70s, but when I shot it in the 80s-90s I hit pressure HARD. I decided that I would give up FPS for stability and went back to I4350. I know that the .270 Win is not the 30-06, but they are close enough to be applicable in this area

That’s interesting… I had no pressure problems working my load up to the maximum load data that Alliant recommended for the 150 gr. I did notice that there was no RL 26 data listed for 130 gr. Bullets. Maybe that where pressures surface on the .270

Or has been noted previously RL-26 isn't very suitable for lighter bullets.

I think @EastTNHunter is talking about temperatures.
Which is odd for RL26 to have swings like that.
I'm guessing they were at the ragged edge pressure wise to begin with.
I shoot RL26 in my 7mm Rem Mag from 18°f-98°f with no issues.
