Anybody using RL23 and RL25 in magnum cartridges? And what results are you getting velocity ( ES-SD ) and accuracy?

Haven’t used 23 much, but 25 a BUNCH! 257 Wby, 25-06, 300 Win Mag, 300 Wby, 7mm Rem and Mashburn Super, and on and on..

And not to be a smart aleck but I wouldn’t use it if it wasn’t accurate. Saying all that, 26 rules the roost with 22, 23, or 25. Haven’t had a problem making it as accurate as 25 and usually a tick faster.

I would never think you were a smart aleck.
I'm sitting here bored since I can't do anything for a week do to a heart catheterization I had done on Wednesday and thought I would use the down time to get more info.
I agree 26 gives the highest velocity of any of them. I saw 3339fps with a 180gr AB before the pressure signs started showing up while shooting a 15 shot ladder.
Just saying Alliant has more load data for RL25 with different bullets in 300wm than any of the other powders it makes.

I've been running RE23 in a 7WSM with 143 Hammer bullets. Accuracy out to 400yds was exceptional with 2" groups being the norm.

I know this is an older thread but is anyone using Re26 for their 7mm Mashburn Super? Would love to hear some feeeback.

I have not , I think it would be a good powder to try . I'm kind of stuck on H1000 in mine .

I use 26 in my 338 Jarret, if I did the math right were at about the same case capacity to bore ratio. 26 is great in the Jarrett, but that is as close as I get.

All I use in my 7mm Rem Mag is RL-26. Good stuff if you can find some.
