R26: 243, 6mm AI, 25-06, 6.5x55, 270, 270 wsm, 280AI, 7RM and 300 WM so far.
In the 338 I would look at R23 data and maybe R16 both of these are pretty versatile and work with light and heavy bullets. It varies on equaling the velocity of R26 but for some loads they can exceed it.

300 WB, 300 WM, 7 RM. 280AI
I prefer classic. Semper Fi I used to run with the hare. Now I'm envious of the tortoise and I do my own stunts but rarely intentionally

I'm using it in 6mm Remington and .280 Remington...both FINE cartridges that Remington placed squarely behind the 8-ball with their *brilliant* marketing expertise. Right behind ya on the 6mm Rem there Andrew.. especially on a long action with a 1 in 7 twist... on the long action, it gives up nothing to a 240 Weatherby... I run 115 grain Bergers at 3250 out of a 24 inch barrel courtesy of RL 19 by the way, using RL 26. Mike, I'd say that RL 26 would be a little slow for a 338 Win Mag... if you are looking for max velocity.. I may be wrong but my 338 didn't impress me much using RL 26 in it... Agree, there probably is a better powder for the 338 WM. IME, RL-26 is great in the 7RM and similar rounds. DF

I think I am at 50.5 gr. in Lapua brass with CCI 250 primer. The mag primer had better extreme spreads. I ran it up to 52.5 grains but holy molly I was getting 270 level velocities at 100 degrees. This is with 129 Hornadays and several other 130s. I think I am at 2,950 fps. for the Hornadays but have not chrono'd the other bullets yet. The 130 Bergers shot really well but too frangible for closer shots to suit me. Same load works in PPU brass too.
This is probably less than max but work up to it. I wanted a load that was good for hot weather Axis hunting so I am probably a grain or so under max. These loads are not for Krags or Mauser 93s for sure.

Gents, post up your .300 Win Mag loads please. Mine historically did well with RL-22 and 180's. I'm using up what's left, won't get any more. All my RL-22 loads are now with RL-23, which, IMO, is a great 300 WM powder. DF

300WM Win. Case 180 Barnes TSX 79.3 gr. R26 Fed 215 primer. for 3,100 fps I just ran up to Alliants max and it shot pretty well so have not done a lot of experimenting.
Will be trying R16 & 23 with the 150 BT next

My 338 Mag load Powder is Norma MRP with 210gr Nosler partitions, Federal 215M primers and Hornady cases. I get 3041 FPS and SD of 8.4 for 5 shots.
Just got some more 338 bulllets so I will try RL26 just to see what it will do. The accuracy with the MRP is excellent.

Can you share your 300WSM loads please! With a 210 grain class bullet would start at 66 grains and work up from there.

MRP is very close to RL-22/RL-23 burn rate. DF

47.6 gr with 147 ELD's in my .260
48 gr with 105 hpbt in my .243AI
43.8 gr with 88 ELD in my .22 Creedmoor
I got over 2800 fps, from my.260, but it was a severely compressed load.

Tried it in my .257R with heavies. There was unburned powder in the chamber, unable to chamber next round until it fell out.
Didn’t bother to clock that one. Best Roberts powder, IMO, is H-100V for velocity and with 100’s, accuracy, H-4350 for heavies. RL-26 probably too slow. Didn’t burn clean.

What other calibers are you all using RL-26 in......? .300 H&H and .30-'06 with 180 or 200 grain bullets.
