so when it comes to self defense ammo, what do you prefer? heavier? lighter? +P??? +P+ ?? i carry winchester ranger 115gr JHP +P+. i like the lighter weight since it screams through the air rather quickly. i think its somehwere around 1335fps or around that. i've heard argument of heavier 147gr for a better knock down power or some shit. never really understood it though. i mean i understand the concept but i never understood sacrificing speed for "power"
