I've tried.
But I found it worked much better in my particular rifle and components used with 250 gr. Hornady BTHP.
So I didn't keep any of the data for 300 Bergers.
Really, RL33 does seem to work better in both of my 338 LM rifles for the 300's, giving velocities up to 2800 FPS.
If you're interested in trying the 250 gr with RL26, I put my particular load below. Obviously you're gonna want to work up to this, using measurements from your cases fired in your rifle, and your choice of components, as the measurements, pressures and velocities will likely be different.
92 gr RL 26
250 gr Hornady BTHP Match
Hornady Case
Federal 215M
CL 2.714"
BTS 2.258"
BTO 2.955" .028" J
COAL 3.655"
3033 FPS
Good luck on your loading!

There's a reason they came out with RL-33.

Just ran a ladder today with RL 26 and 300 Berger's and 270 ELDx. Fed 215M primers and 28" Carbon Six 1-9t barrel with the 300 Berger's
87.0-2838 2842
87.5-2842 2852
88.0-2844 2833
88.5-2855 2875
89.0-2879 2893 Slight Ejector marks, had to turn just right in the sun
89.5-2932 2904 slight ejector marks
With 27" Lilja #6 1-10t barrel and 270 ELDx @ 300 yds
88.5 - 2897 2902
89.0 - 2908 2878
89.5 - 2904 2895
90.0 - 2925 2955
90.5 - 2953 2961 2981 shot as 3 shot group just over 2"
Was really too windy but really wanted to shoot, 15-20 with gusts to 27 outta my 10 o'clock. Hell we even had a bit of mirage today, sunny 50°F. Encouraged by what I saw.
