    A couple of listings have said that if you don't have load data for a particular weight bullet, it's okay to use the load data for the next weight bullet up.

    Well, what if you have load data, but want to use a different powder listed for the next bullet weight up which is of a similar bullet type? Ok? Bad?

    With that said, if the powder is from the same company as your load data, you can usually compare other loadings and derive a ratio. Powder burn rates are generally stable, so if a similar cartridge runs, say 2 grains behind another powder, it's usually pretty close.

    If it's from a different company, you may have to call their tech support and ask.

    Certain powders can spike strangely. If you don't find any data on that powder for that bullet type and weight it's probably so far out of spec as to not be able to produce decent velocities at safe pressures.

    Do you have a specific example you're interested in?

    Black Snowman: I am looking at the very few loads I have available since I haven't picked up another manual yet for 44 Special and my 225 grain Speer bullets. The loads for 225 JHP list 4 powders and starting weight, Red Dot (4.9), 231 (5.0), 2400(11.6), and IMR-4227 (12.3), while some 240 grain jacketed loads from the Lee insert lists an AA#5 (5.8) load that I wanted to try (I have the powder)but I have no certain data to try. That was the main reason I asked. I never got around to being able to go get some Red Dot powder today.

    Just did a quick look at there web sight. They list AA5 for 240gr jsp
    5.8grs to start and a max of 6.5grs.

    Check out the cost of reloading thread at the top of the page. There is
    a large list of links to suppliers.
