New to the 44, why would you not want to shoot 44SPL? I have 100 rounds of HSM 44SPL I picked up on sale to break in a new 629, but will reload mostly. Have dies and 240gr bullets, but no brass yet, figure I will order 500 from Starline... So it's better to load 44MAG brass instead of 44SPL regardless of load (light or std)?
