Reloading the .44 Magnum with 300gr CMJ

Using South African Somchem powders, and copper jacketed bullets. Scale used was an RCBS 1500 , chronograph a CED M2.

A practice load for ESR. It's 50% higher than required factor, which seems contradictory to the purpose, but my hunch is that training with higher recoiling ammo in a revolver makes for much better shooting when using ammo for factor.

If you choose to duplicate any loads here, or use these loads as a basis for your own, use 10% less powder and work up from there.

Do not attempt any of this if you have no chronograph to verify bullet velocity.
