    At one time I remember seeing a listing of ALL Powders and their Burn Rate in relation to one another.
    Anyone know where this is listed??

    Clearly caution is advised using any of them, since they disagree in so many places. But as a general comparison they are fine. They just aren't reloading guides, that's all.

    Neil, You are on the money on that one. There are MANY discrepancies between these charts. The main question is, why would anyone need to use one of these? It is NO substitute for reliable loading data. Powders can perform differently in different loads and conditions. Under some circumstances, a "slow" powder can become a "fast" powder and vice versa. Selecting a powder should include looking at reliable data for the loads you wish to assemble, including an assessment of pressure and velocity developed. That would give way more information than a burn rate chart.

    Now than;

    Having posted sever burn rate charts, Niel has stated it exactly. "ONLY" use published loading data. In my opinion these burn rate carts are only a general guide to compare different powders and ARE NOT to be used for loading data!!!!!!

    The following URLs will provide all the loading data you may need, "USE THEM".

    Copy and paste the following URLs.

    Please listen to whats said and dont plug in powder just because it looks close to what you have.
    I can print a burn rate chart from Sierra that differs from what you see, the same from Hodgdon. Lee

    Like they said - just use the powder guys loading data.

    It's only a shotgun, get over it - it ain't ever gonna be anything else.

    JMO of course cuz in America you can do anything you want

    You don't need a burn rate chart unless you are trying to develop your own loads in close partnership with one of the ballistics guys that does pressure/velocity testing for the general public.

    Use published data. Don't try your own substitutions based on some chart!!

    I agree with all that's been said about using published data. The only thing that I can see that is useful about a burn rate chart is to ballpark an application (not charge weights) i.e. 800x and Accurate No. 7 or 700x and Green Dot are next to each other so they can be used for similar applications and you will likely find data that will work for the same type load.

    Thanks for mentioning Green Dot, James, since it summarizes what's wrong with these charts. Consider GS Custom Bullets ratings. There you will find Green Dot below 7625 which hardly seems right, but it probably is not as misplaced as Winchester Super Target which finds itself called faster than Bullseye which is an unfamiliar neighborhood for it I'm sure.

    Ramshot, on the other hand as you suggest,. puts Green Dot with 700-X though I'd say that in that comparison it's the 700-X that's in the wrong place, not the Green Dot

    And so on.

    Yeah the reloading bench chart is the same as the Lymans. Both don't have PB listed. Dave T.

    Mash the link above. The author says the data is virtually meaningless.

    Powder burning rates can be useful in selecting a new load, but it is important to understand what both the burning rate lists and reloading manuals are designed to provide.

    Reloading manuals provide the components for safe loads. But, safe loads are not the same thing as the best loads. For light loads, a fast burning powder will give better results than a slow powder. For heavier loads, slower powders work best. I remember how wonderful the published data for 800X in one ounce loads looked in a reloading manual. I also remember loading some of the very worst one ounce loads ever made because I only relied on data in a reloading manual and did not consider burning rates.

    For light one ounce loads either Red Dot or a powder with a burning rate close to Red Dot is excellent. For heavier loads, Green Dot or a powder with a burning rate similar to Green Dot is excellent.

    A burning rate chart can help guide you toward a powder that will do the job you want it to do. A good reloading manual will tell you how to safely use the powder.

    Most rifle & pistol loading manuals have a powder burn rate chart listing all the powders commonly available to when the book was printed.

    Looked at one the other day and it relected that Green Dot was a faster powder than Red Dot. That can't be true, is it? BT-100dc
