Have started to carry a 9mm a lot . Carrying 147 gr Winchester SXT also got 115 gr Federal Hi-Shok (not Hydra's) due to real cheap for now and just wanted something else. What other type should I look at mostly only carried .40's and .45's 180 gr 230gr Hydra. Shocks and SXT 's . Is 147 gr to heavy for 9mm? I thought since it is a heavier bullet moving slower would have more force then a lighter faster one. Is this not right and what type of bulletis best for expansion? I know everyone has there opinion I want to hear some.
