    Looking for 250 gain and up loads for Milsurp HS-7 Speed in 44 Mag

    I have a good bit I want to use to send lead projies down range.
    Looking for any HS-7 loads for 245 and up to 300 grain boolits.
    Mild to serious hunting loads would be appreciated.
    Nothing is impossible for the person that does not have to do it.

    Speer #12 manual shows 13.8 - 15.8 gr. HS7 with a jacketed 240 gr. bullet and a magnum primer. Velocities run 1124-1249 fps. No HS7 data listed for 300 gr. HS7 data is hard to come by since it's been discontinued. But it has the same burn rate as Blue Dot, and from what I've been seeing in the manuals, they use close to the same amounts for given velocities. If you can find data for Blue Dot, I'd start 10% lower with HS7 and work up.
