This powder by Hodgdon:
US 869® Shawnee Mission Kansas, Hodgdon Powder Company leads the way again by developing an outstanding 50 BMG propellant that offers significant advantages in many magnum rifle applications! US869 is a true magnum Spherical rifle powder that is superb with heavy bullets in big, overbore rifle cartridges. US869 is a dense propellant that allows the shooter to use enough powder to create maximum velocities in cartridges such as the 7mm Remington Ultra Magnum, 300 Remington Ultra Magnum, 30-378 Weatherby Magnum and others. US869 is superior in the 50 Caliber BMG where it yields high velocity and great accuracy with 750 to 800 grain projectiles. This is a fine 1000-yard match propellant! In addition, US869 is effected minimally by varying temperatures, a key feature for top competition and hunting accuracy.
Hodgdon’s new US869 will be at dealers everywhere spring 2006. For complete US869 data check the new 2007 Hodgdon Annual Manual, visit www.hodgdon.com, call 913-362-9455 or write to Hodgdon Powder Company, 6231 Robinson, Shawnee Mission, KS 66202.
I haven't got any thing (yet) that big to use it in.

Nice enticing write-up.

Well Hodgdon wrote it as advetisement for the US869 powder, it appears to be new. I wanted others to be able to view the data I researched and posted the write up for others to see. Their load data shows some strong loadings for it on the web site for your rifle.
Remington 300 Ultra Mag
200 GR. BAR XFB 200 US 869 .308" 3.555"
Grains Vel Pressure
96.0 2834 58,000 PSI
100.0 2919 61,800 PSI
Rumbtubo is very close to same velocities but produces more pressure on the max loading side.
Good luck with your testing if you try it.
Wade
