Recipes for .300 RUM and H4831

[MWecker]

With the limitations around all reloading components like bullets, primers and powders, I put myself in a tough spot with my .300 RUM. I have 220 gr. Sierra MatchKings and 230 gr. Berger Hybrids, which I can get extra stock online. I'm left with VERY little Retumbo, no H1000 or any RLs. I know these powders are ideal for pumping these heavier bullets accurately, but I'm screwed there.

So the question being, does anyone out there have recipes with H4831 and the 220-230 gr. bullets that work with .300 RUM? I'm too hesitant about making my own starting concoction without wasting time and my limited resources on hand.

What I have on hand:
Factory Remington 700, 26" barrel.
Once fired brass.
CCI 250 primers.
1.5 lbs of H4831
220-230 gr. pills

***Something of note, I have not yet shot this rifle. Just traded my .300 WM with good compensation for this .300 RUM. I'm using this rifle for long range hunting/target shooting. More likely target fun.

Please do not load anything 4831 in a 300rum with 230gr bullets.
If you were loading 150gr or lighter H4831 might be an option. These powders in red parentheses are the ones that would be appropriate. You want as close to 100+ % case fill as possible.

Surprisingly, Hodgdon does list data for H4831 loads in the 300RUM:

Not surprising, as @46and2 states, is the lack of H4831 listing with heavier than 200 grain bullets.
The 300RUM can be a very good performer with bullets down in the 200-215 grain but still not recommended with H4831. My advice would be to just keep looking and keep hoping. I found an 8# keg of IMR7977 (H1000) at a very decent price in a local to me store couple weeks ago.

Nosler lists load data for their 220gr custom competition bullet with H4831sc. I’m sure you could safely extrapolate load data for either the Sierra or Berger bullets using that data. There’s nothing inherently dangerous about using h4831with heavy bullets in the RUM, you just won’t get the best velocity.

Pats reloading WC872. its cheap

Isn't there WC860 around as well?

Yes But i have no personal experience with WC860, and i will not guess like some replies on this board. I shot some Sierra hunting 338 bullets just to do barrel break in and had very good groups with WC872.
