I think the important part here is consistency.
Since the vast majority of USPSA stages start loaded, I always load 11 in my first mag pouch. Always.
This way I get an extra reload rep when I LMR.
Personally I think a shooter is doing themselves a disservice by loading from a back pocket or anywhere other than their mag pouch when possible. My opinion.
For an unloaded stage, I just strip out a round no big deal.
I too am considering just shooting limited minor. With 23 round reloadable mags that might just make up for shooting minor. Heck, As are 5 points minor or major and that?s what you should be shooting anyway right?
