I'm loading 9mm with 5.0 grains of CFE Pistol and a Lee TL356-2R. Velocity is right at 1000 fps. I've never had a misfire or FTF with this load, but the bullets are tumbling. I've noticed that my Taurus G3C has very shallow rifling. I suspect that the lead bullets are traveling too fast to get a grip on the shallow rifling. Appreciate any input.
