Guys, I got awesome advice from this site. There is no load data for PB Pistol Powder for 9mm 115gr Hornady Round Nose FMJ. However the folks told me to use Speer Dot load data and my range for FMJ round nose is 3.6 to 4.0. However, after using 3.6gr, my action on my Shield would not cycle and kept jamming. It was quite obvious the load charge was way too weak.
