New to reloading, just wanted to ask a quick question for perspective. What is the optimum FPS to hit with loading 9mm. I am shooting 3 gun and not concerned with power factor other than other than needing reliability, accuracy, knocking down steel. I have shot loads in the 975fps, 900, 875, 850fps. So far my pistol has fired all with no malfunctions, and I have knocked down heavy poppers with all of the above. I was told to target 925fps out of my pistol, but I am not certain which way to go. I bought some Atlanta Arms 147's and they chrono in the 870's, they shoot really soft and I like them.
I really like shooting the ones in the 875-850fps range as they are really soft and shoot well out of my gun. My main question to all this is there an issue with pressure spikes in the casings, added pressure to my pistol if I consistently shoot the softer loads? I just want to make sure I am being safe, do I need to keep my velocity in the 900 range to avoid those worries. I would appreciate any advice
