My FIL hasn't reloaded for his .44mag (Ruger Blackhawk) in many years. His 2nd edition Sierra manual (1978) lists the max load of Alliant 2400 as 23.3 grains for a 240 grain JHP. Alliant's website lists the max load for 2400 as 21 grains for a 240 grain JHP.
When he developed the load for his RBH, he settled on 22 grains of 2400 and has fired many those loads. Is it safe to buy a new bottle of 2400 and use the same load or has 2400 been reformulated?
