I shoot a 5" .44 mag. Since most load data was originally developed with longer barrels in mind, I obviously get more muzzle flash/blast than those who were developing the load. If I want to choose a load with one goal being to minimize muzzle flash/blast from my shorter barrel would I get more benefit from: A), Going to a heavier bullet (which also uses less powder)? Or B), Choosing a slightly faster burning powder. Or, maybe both?
