RL-26 vs 4000MR

[Accumark]

First let me say, I have read many of your posts and I am impressed by the amount of knowledge posted here. So I am curious if any of you have experience with 4000MR and how it compares to RL-26. I getting ready to work up some loads for my new Fierce Edge 300WM. I have a couple of lbs of 4000MR along with a couple lbs 26, 25 and H-1000. 4000MR seems to more available than 26. I will be evaluating Nosler 190 and 210 ABLR, Fed 175 and 200 TLR. Any help would be appreciated.

H1000 and 26 will be your friends. I'll take the stability of h1000 over the additional fps of 26.
Most double based powders are temp sensitive, so 4000mr isn't on my radar.
If you want the cheat sheet, 75.5-78 grs of H1000 and a 215 Berger is primo in a 300 wm.

I've also never used 4000MR but currently using 75.0gn, RL26, BR2's with 215gn Berger Hybrids. Relatively new, 28", 1-9t, Pac-Nor barrel and I'm getting 3045fps with no pressure. I ran a Ryan Mantha finish reamer in my chamber to seat the 215's out farther than SAAMI spec.
