What is the advantage/reason for loading longer oal ? I've not been loading 9mm but a year or so, and not a lot rounds in that time. In researching, I see a lot of people load to the max (PLUNK) and then back off a few thou. Most of my reloading is mimicking the Factory ammo(124 XTP +P)I use in my "carry" pistol, and I just load to the same length as the Factory stuff, or just a tad longer.
Mostly just curious.
