    I have a file/list that I made in Excel format,
    for the burning rates of powders in closed bomb tests,
    also in the same file there is a Heat index of the heat units of that powder,
    and powder heat of explosion.

    A Different type of Powder chart

    I have attempted to contact 2 different Mod's about posting this info,
    and have not received a reply back,
    so I believe that it OK to post this chart.
    I guess I'll find out??????

    Here is a chart I made up, of the 140+ Us powders, it is current as of 2015.
    Sorry for the rough formatting, but I lack the computer skills to understand
    the proper formatting for this site.
    I used MS XL formatting and I am able to search thru each column for any powder I am checking on.

    When posting here, using the XL format, it don't look as nice, as on my plastic's box screen.

    Burn Rate Factor--------------------------Powder Heat of explosion---------Ratio of specific Heat
    Fast to Slow-------------------------------Hot to Cold-------------------------Hot to Cold

    I'm sorry, Don but I don't understand your chart and the numbers.

    From this small sample of data, it is hard to understand, so I'll give you an example,

    Lets say you are using xyz powder,
    you find thru testing that this powder is just a hair too fast/slow for what you want to do,
    or you want to see if there is another powder that is the same spec's, or very close to your powder etc.

    You can go to this chart and see which powder is on each side of that powder,
    the chart gives you the spec's of each powder as used in reloading ammo etc,
    not a generic SWAG that is posted some where, ie, H110 and Win 296, are the same,
    you will find that they are not, if you compare the same spec's of each powder etc.

    There is 3 sections of this chart, that is listed below,
    (I can't get the explanation of each of these areas posted with the proper section because of the formatting etc,)

    Burning Rate of EACH powder =,
    Powder heat of explosion =,
    Ratio of specific heat of that powder =.

    I am asking for some HELP from some members that knows/understands how to format this chart for posting,
    so the total info can be posted here for everyone use etc.

    Once this chart is properly formatted and all the info/spec's are posted,
    it will be a lot more clearer to understand and use, IMHO.
    Once posted, there is a good chance that it will be made a sticky,
    via info from a MOD, I just received.

    This chart covers the 140+ US powders available.

    So, can some member HELP me with the formatting etc,
    and get it posted here??

    You'll have the 1st copy,

    Another chart I'd like to see would compare each by volume so I can try to maintain approximate load density in a couple of my target rifles. My Lee 'slide rule' is handy for this but it was printed in 1995 and doesn't include anything introduced since then.

    I hope this thread is appropriate for my question.
    Has anyone determined a significant difference between Re 7 and AA7 ?
    The way is ONLY through HIM.

    aa7 is a pistol cartridge powder, good for 9mm Luger, 40 s&w, 45 auto, 357 mag, 41 mag, 44 mag and more
    re7 is a rifle cartridge powder excellent for many straight wall rifle calibers such as 375 Winchester,444 marlin, 45-70, also good in many other cast rifle loads
