stable/consistent 300 WM powder

[NCHillbilly]

I am beginning to build some test loads for my RPR in 300 WM and was curious about what, if any, powder(s) showed good thermal stability and lot to lot consistency. I'll be loading mainly heavier bullets (190-225grs). I have 1lb cans of the popular wm powders: H1000, H4831sc, H4350, RL-22, and RL-25. Any of those a winner? Once I settle on a couple of good loads, I'll buy bigger jugs of powder.

H1000 seems to be the standard

+1 on the H1000

Good, I have a couple of pounds of that already.

I run H1000 with my Berger 215 Hybrids

I run the 215 hybrids with H1000 as well.

Seems like I would do well to try H1000. Thanks guys.

Retumbo also works well. But I have plenty of H1000. So that is my go to.

Yeah, H1000 is kind of the gold standard. With 190 grain bullets I get the most consistency and lowest SD with Reloder 23.

same here. I run H1000 and 215 bergers.
