I'm look for some advice on loading some 9mm very light loads. Pistol is S&W 929. Bullet is 115gr powder coated . Powder selection is BE, UNIQUE, 231, tightgroup, red blue green dots, autocomp and CFE pistol. Was leaning towards the BE tightgroup 231 as I think they would be fast enough. The goal is to load a very wimpy load used for indoor cardboard shoot comp. I was looking at 38sw data as case capacity is close but figured I would ask if anyone has any experience with mouse fart loads
