    I am looking at the Reloading Data Center at the IMR/Hodgdon site and they are showing loading data for all of their rifle loads but they do not recommend a primer to use. Why is this?

    ask hodgdon's could be because they don't make primers.

    It really doesn't matter much with metallic as long as you don't use a Magnum where it's not called for. My reloading books do not list any primer other than stating small pistol, large pistol, small rifle, large rifle and Magnums where needed. Also the obvious is do not mix small rifle and small pistol or large rifle and large pistol primers. Never never never use a Magnum primer unless the recipe specifically calls for one. I use Winchester primers for all my centerfire metallic loads.

    With reloading center fire rifle the pressure level is high enough that you can see when you are approaching too much pressure. Flattening of primer is one.

    So follow GrnTitan's post about the primers and take the lower end data, work up to the best grouping, stopping at the top end.

    If only the "Maximum" is listed the rule of thumb is start at 10% less and work up.

    Thank you young gents!!!


    I do like that they give the lower pressures and weights then the max. I will start low and work my way up.

    Thanks Again

    Hodgdon does in fact, specify primers for their rifle and hand gun loads. Getting to where it is listed requires multiple steps. You have to drill all the way down into the data.

    Here's how it works...

    1. Using Hodgdon's on-line reloaders guide, specify "Cartridge Loads".

    2. In the second step pick "Rifle" or "Pistol" in the "Load Type" field and the caliber you want in the "Cartridge" field.

    3. The screen you get at this point lists every load Hodgdon has for that caliber including every bullet type, bullet weight, and powder they tested.

    4. From that screen you can narrow things down by picking a specific powder and specific bullet weight. Click on "Get Data" and you'll get a single load. However, it still doesn't list the recommended primer.

    5. To get the primer click the "Print" option. That will take you to a 'printer friendly' screen listing all the details for the specific load you picked including (at long last) the primer Hodgdon tested with that combination of components.

    Hope that helps.
