Allow me to start off by saying thanks for the patience! I know at least the first question must have been covered before. Can the 9x19 be trimmed to 9x17? I cant see an issue with this, but I dont want to find out you cant the hard way... For you casters out there: What can be done voluntarily to effect change in the .380 round to allow for more reliable expansion? Is the issue related to the jacket? Perhaps a softer bullet itself would facilitate more effective expansion? Could a deeper cavity make the change I would like to see? Can any of these things be done without bleeding off massive quantities of penetration? Please! Someone create a .380 round that will end this ".380 isnt effective" debate that we always hear! Thanks again.
