Try ramming them through a 5 gal pail of packed damp earth to see how they expand and compare them then. A hay bale to form an opinion on expansion???
I really doubt that you will see much of a difference. The Barnes all copper and the Nosler Partitions will expeand to a given point and quit expanding... but that has nothing to do with the with the depth of penetration (well really it does) but those bullets are designed to expand and with the weight that they have behind the expansion barrier - they will continue to drive as long as the have energy. The design of the two bullets - gives a known expansion almost everytime - then depending on the the energy they have at contact the penetration can be calculated in tissue. Nosler have been tested over and over and will achieve proper and uniformexpansionthrougha greater range of velocities than any other bullet. Right with that are the Barnes "all copper bullets"
With the price of lead climbing so bad I thought the switch to Barnes might be the logical short term move - but copper prices are climbing just as steadily.
