First, its not about the fps. velocity has nothing to do with it. It is chamber pressure vs alloy hardness& size that matters. the 9mm luger pushes 35000 psi. I cast my Lee tumble lube 124 gr RN bullets to around 18bhn, lube them, size them then lube them again. Im sure not suggesting you do it, but i have run these bullets(100 rds at a time) through my glock 19 with both 5.0 &5.5gr of power pistol cleaned just after each shoot and have never found any lead in my barrel. Use your better judgement, but this is my experience.
