    H1000 .5" Groups, holds MOA or less out to 1400yds with a 208 Amax in 300WM & 300RUM am looking at 215 & 230 Berger Hybrids, only bullets that might be better.

    I have read and it seems most everyone likes h1000 and ratumbo. But can't find it at the gun stores yet. So looking for other good options. Few people talk about the 4350 also......might have to look for that. Some talk about r22 I think it is..... Anyone use that?

    I have tried RL25, RL22, IMR4831, H4831, IMR4350, H4350 and RL19. All produced sub MOA. Presently using H1000 because I got best accuracy EVER with this powder (79.0gn), 190gn SMK and CCI250's. Shot sub 1/4" at 100yds. YMMV. JohnnyK.

    H1000 is a favorite. Retumbo is a bit slow, but it works for long barrels and heavy bullets.

    H4831SC works surprisingly well for bullet weights up to the 215 Berger. If you can find a bottle it might be worth a try.

    Ramshot Magnum and IMR 7828 are both great powders too. From what I've seen they are both great for velocity and temp stability.

    RL22 is also worth a try. You may find that it isn't nearly as temperamental as many people would have you believe.

    Look for another thread I started about powder for 300 mag. I am in the same boat. H1000 is not that good in my gun. Gonna try others
