44 mag load w alliant 2400 & 320 gr bullets

Looking for a known starting load here.

thanks

Is it a cast or jacketed? is it for a rifle or a pistol??? I have reloaded 300g . I got my data from powder manufactors

new to site haveing a hard time Just noticed your ? was in the pistol section.

They are cast bullets with the gas check from a revolver (handgun)

The powder company does not cover 320 grain bullets last I checked.

Hi Ray,
Welcome to Gunloads. In a case where you have published loads for a jacketed bullet and want to shoot a cast one that is slightly heavier, you can go with the published data for safe starting loads.
For a .44mag with 2400 and a 320 cast, Sierra, under 300 jacketed, lists a starting load of 16.7gr @ 900fps and a max of 19.1gr @ 1050fps. Data was compiled with a Ruger SBH.
