Follow up question.
If POI for different bullet weights and types is several inches apart left and right, what can be deducted from this?
I would deduce that you can't use those loads interchangeably for accurate shooting at extended ranges. It happens to me all the time when shooting factory rifles with light-taper barrels, with scant exceptions. I've loaded for and shot some heavy guns and heavy barrels that behave differently, as a rule.
