The Light Magnum cartridges required specialized machinery to charge the case and seat the bullet on a compressed blended charge. Not something you can expect to do safely at home.

IMR 4007 Powder is a "Super Short Cut" extruded single base that was formulated for good velocity at low pressures. Hodgdon load data for this powder duplicates the MkVII loads with pressures of less than 40,000 CUP.
Have yet to find this powder locally, and have heard little of it since it first came out.
Kanamco, sucessors to Kynoch , use blended powders to duplicate Cordite loads for older British African big game cartridges and the .303. Pressures are low for velocity achieved.
