    Here's a place to start- http://ns.hodgdon.com/extreme.html -I'd highly recommend using a powder within this group.

    Then use a chronograph to work toward a reasonable velocity goal and pay attention to pressure signs like head expansion, primer flattening and stiff bolt lift.

    Off this topic, but what load data might you have for your .416 Taylor? I’m close to buying one and would appreciate your input? 350 and 400gr bullets. Thanks!

    Manufacturers blend but they have the facilities to test for burn rates and pressure. Their blends are consistent.
    If we start blending I can only imagine the disasters they would occur.

    I figured that.
    I couldn’t imagine anyone from AH being so stupid as to try it!
