Has anyone on here tried using 50BMG powder in replacement of not being able to get H870. It is really close on the burn chart. I am wondering what a decent starting point would be. I am wanting to go this route because I am to get a better case fill.

Re: 50BMG powder in 300RUM?
With 200 to 220 grain bullets, try 90 grains and work up. May be a bit slow but should be safe. Use magnum primers. JMHO

whats the load data you use for 870 and 862 and im pretty sure wiedner has plenty in stock
I used to use 50BMG in my 30-378 and it was the most accurate powder for 180gr bullets. Retumbo gave me more velocity but I still prefered 50bmg HTH

I've used quite a few 50BMG powder's in 338LM. It will work in a pinch for the 300RUM. Lower velocities for sure. You need longer barrel to take advantage of the SLOW powder. Most loads will be compressed or at least close to it-if you use a stick powder. US869 works very well and meters very nice.(ball powder) QUICKLOAD program is VERY useful trying to develop loads with non-standard powders. I really like Hodgdon Retumbo with large cases and heavy bullets.
PS: Widener's doesn't have any Military canister powder's in stock.

The powder is too slow and will not burn in even a 30" barrel. With that being said, you can still use it to load some cheap (and sometimes accurate as noted above) rounds. It won't give retumbo velocity, but it will also be easy on brass. Hard to KB a rifle with powder that slow also.
