As the title says I am looking for very specific load data (based on what is most readily available in volume to me) for my Remington M-700 5R AWR .300 RUM.
I would sincerely appreciate any guidance with regards to this powder and bullet in this cartridge. Thank you all very much in advance.

FWIW, didn't find much. Berger doesn't use US869 until the 30-378. Maybe there's a reason.
 
Sierra VI manual lists their 210gr HPBT Match should be close to ur Berger, using US869 with a starting load of 86.9gr @ 2,600FPS. Going up to 88.9 at 2,650fps, 90.9 at 2,700fps, 95gr at 2,800 fps, 97.1 at 2,850 fps, and 99.1 gr at 2,900 fps and 3,921 ft. lbs. energy. COAL 3.820"

My Berger 1st ed reloading manual does not show US839/210 Berger for .300 RUM, but if you contact Berger's Tech Support, they will provide you with their latest load recommendations that might include the US869. Good luck!
 
I have the same gun and my nephew too. We both shoot n570 and 225 eldm hornady cci250 my gun is 90 grains and his is 89.7 speed is 2930 fps both guns shoot very well Norma brass
 
I tried it in my 300 RUM, a Sendero SF when I ran out of Retumbo. It shot well, it was just a little less velocity. 210 Berger VLD, 100.5 Gr US 869, 3.65" COAL, Fed 215.

Note- This was in my rifle, I had no signs of pressure, but case was full and velocity was 2823 avg over 10 shots with an ES of 14.

We did put Wyatt 4 inch boxes in them I’m 3.91 oal and I’m probably going to have to move it out a little more soon it’s a barrel burner I’m going to have to not shoot it very much or decide what barrel to replace it with
 
I shoot Retumbo in my 300 RUM with Berger 210 VLDH bullet. I also shoot Retumbo behind a Berger 215 HT. Both loads use R-P brass kit by a F215gmm primer. Both loads are under 1/2 moa consistently.
 
QL says @ 105% case fill you are still down 3000psi, and 100fps, only achieves 96% burn in a 24" and the muzzle pressure is among the highest (lots of blast), compared to the best choice.
If your barrel is 26" this may be a bit better.
The Nosler data above says 109% fill. And still is not the fastest.
Find out how much you can stuff in YOUR brass on average then tweak downward as accuracy demands. Basically this powder is too slow and or bulky, for this combo, BUT usable.
 
I’d use retumbo or RL25, one hole groups for me with the nosler listed data with several different 200 ish bullets mfg I like the 200 accubond best but the eldx not far behind
