Newbie to reloading here so I appoligize ahead of time if this is a dumb question. Since both .380 and 9MM bullets are .355 diameter can the smaller grain 9mm bullets be used for reloading .380s? The only restriction I can think of is if the 9mm bullets are longer consequently making the OAL of the round too long for a .380.
