Sounds like VooDoo to me.
I put 80% of my time into developing my long range loads. Those are the critical ones that require utmost accuracy and low extreme spreads. I load these cartridges single-shot style only, and never place them in my magazine. I don't want the tips being dinged under recoil, or any other surprises.
I put 20% of my time developing the shorter range loads. These bullets are seated to fit the magazine, and are the shells I carry in the magazine. They're a stout bullet of some sort that still shoots well enough to hit and kill game out to 5-600 yds. These are my carry in the chamber and magazine loads. Camp loads also. If a bear comes into camp or charges while I'm walking about, these are the bullets/shells intended to stop a black, grizzly or brown bear. But they're also the loads I'll shoot sheep, caribou, moose, deer, goat, etc., if the shot is less than 500 yds, because they will likely cause less unecessary meat damage than my long range loads would at those closer ranges.
I've never experimented to see if alternating loads would cause POI changes. Maybe others will sound in and identify that as a problem - I haven't seen it and remain skeptical that it's a problem. As a last resort - say that it is a valid concern. It still wouldn't keep me from continuing loading and carrying two separate loads. On the majority of my hunts, the animal is dead after one exhange of gunfire. Then that trip is over and the barrel can be cleaned before the next hunt.
