    I havent had good success with IMR 8133 in my 300 rum yet. RL33 has been decent . H1000 good. RL26 and N570 I have now but not tried yet. N565 and N560 should be good. I still have 5 pds.of Retumbo. I've used and liked it for years.

    AA8700 was a great powder. It's been discontinued and I can not find any reloading manuals that still list it.

    How is the temperature sensitivity with N570?

    I have also had good results with 7828 in 7mm RUM.
    Just wondering if I should look for a more temp stable powder.

    Been using NV570 in mine with the 195 Berger, shoots great with good velocity and isn’t as dirty as RE-33. Temp stability isn’t too bad on it. Shot h1000 with 180 Berger’s but never the 195s.

    Lots and lots of data and customer accounts that says otherwise......US Military is also buying up most of the N570 produced for a number of reasons, but one being temp stability.

    50BMG is readily available here. All the other recommended powders are out of stock. The only thing I can find is one 8lb jug of H-1000. Pretty steep purchase when I don’t even know if my gun will like it.

    I’m running 8133 in 2 different 28’s, having pretty good luck with it with the 195’s. I started @ 73gr and worked up. Running 78.7 currently and getting 3035 in one gun, haven’t chronod other one yet. Just getting done with break in.

    If your wallet can stand it and you can get your hands on it, use Vit 20N29. incredibly stable SD and ES across a wide range of temps and very little cold shot to hotshot deviation. It is also very very clean and peak temp is lower than most so barrels last well.

    You will be able to get a perfectly filled case with no airgap and that reduces variations even more.

    Good luck!
