Incidentally, "experience" has NOTHING to do with physics. The bullets do what they do whether you've shot no bears, or thousands. It doesn't matter. It's physics.
Each one is an example of one. Variables are the uncontrollable factor.
Experience and experimentation matters greatly. Figures on paper are no promise of expected result.
Calculated sectional density figures are not the only factor to be concerned with. Only a starting point.
