Stable powders

I have been using h-1000 in my 338 lapua and I like it, I was just wondering how temperature sensitive is h- 1000? would I see a big benefit since I shoot when its 0 degrees and when its 80 degrees by switching to a less sensitive powder? if so what do you guys reccomend?

    fantastic thank you!

    is there anything out there that is published saying what powders are stable or non stable? or a rating system of some sort? that would be really handy.

    somebody out there hopefully will have better information, but generally the Hodgdon powders that are identified as the Extreme powders are stable.

    H-1000 is one of the Extreme powders.

    Re: Stable powders

    I think I read on here recently in the reloading section, that single based powders like H1000, Retumbo, H4350, etc are temp stable, where as ball powders or double based powders are more sensitive, ie reloder 22, etc. I believe alot of the IMR powders are single based as well, 4064, 4350, etc. Perhaps someone will correct me on this though.

    Re: Stable powders

    Hear is a list of extreme powders (Not sensitive to temperature changes) that I know
    of for rifles in there approximate burn rate from fast to slow.

    H4198
    H322
    Benchmark
    H4895
    Varget
    H4350
    H4831 and H4831 SC
    H1000
    Retumbo
    and H50BMG

    These powders are the least sensitive to temperature as far as I know.

    This does not make them the most accurate, just the most consistant in all temperatures
    ranges.

    I hope this helps.
