Happy weekend! Concerning CCW/SD/HD, I hear of various people mixing loads in their mags. Mixing controlled HP, HP and ball ammo in a mag to have a range of penetration, expansion and everything in between in a few shots. What are the pros/cons of this, all together or separately for the above three uses? Of course this is all assuming that the individual rounds feed well in the firearm. I've always carried my round of choice by itself. But I've always wondered if there is any merit to the logic these people use for their choices. Thanks!
