I don't see how sectional density and ballistic coefficient are going to affect felt recoil. Idahoguy101 asked about recoil.
When you are measuring effectiveness on game comparing SD's is far more accurate than bullet weight...
Comparing SDs of say .270cal 150NP vs .30cal 150NP is ok, but SD is not a reliable method of determining comparative bullet performance in the case of
.270cal 150NP vs 30cal 150 monometal....because it ignores important differences in construction and design that effect terminal performance.
Idahoguy101 in his orig Q. said nothing about like construction and/or brand of bullets as a requirement when asking about RECOIL between 150gn bullets.
Nosler data:
.270win 150gn R19 55.0 max
.30/06 150gn R19 61.5 max
more powder = more recoil = question answered without all the distracting tangents he didn't ask about.
Comparing effectiveness of a 270/150 to a 30-06/150 on game
isn't a fair comparison, the 270/150 is a much better choice with similar recoil.
270/150 is a better choice or not? , or 270/150 vs 30-06/150 a fair comparison or not?
really depends on what actual type/variety of bullets you are comparing.
A 30cal 150 mono may have very simliar (or even less) frontal expanded area and retain similar(or more) weight, than some types .270-cal 150 cupcores
which makes the static unfired bullet SD comparisons people use in determining terminal performance, unreliable.
Although SD will be the same in a range of cup-cores in same weight & calibre(or a range of monos in the same weight and calibre) it can still be misleading
in regards to terminal performance outcomes.
