I'm new to reloading and downloaded the Reloaders Reference program, I looked up the 357 mag load for bullet I am using. It said 8.4 grains of Longshot so I loaded 100 rounds. After doing some research I found that the max SAAMI pressure for a 357 mag is 35,000. The load data I used says it would be 43,200. I haven't shot any rounds off yet thinking this might be too much for the Henry Big Boy 357 mag. Should I go ahead and shoot them off or should I reload them to a lower pressure?
