has anyone had the opportunity to use hodgdon us 869? Any powders that I would like to use are unavailable or hard to come by. I see us 869 available on a regular basis that it's starting to haunt me. Burn rate suggest that it may be ideal for the .338-378 weath. mag. but data is non existent.

US 869 was one of several powders I tried out when developing loads for a Nosler 28 with the Berger 195 EOL. I was able to achieve 3070 fps. These were development loads so one should reduce starting loads accordingly.
I'm not sure if this helps except to show it can useful for overbore cartridges.
I would recommend running QuickLoad or similar software to ballpark starting loads for your caliber.

I wish I could help.
I have a 30-378 and it likes Retumbo, N-568, H-1000. Just to name a few.
Hopefully someone will join in that can help.

Thank you so much for this data, definitely looks like retumbo is an excellent powder for the .338- 378 weath. mag. I have about 21/2 pounds of retumbo; so I guess I'll start there. The availabilty of us 869 at reasonable price is why my interest in us 869.
