Interesting you say
with two different calibres the protected points appear to be a little less
stable when penetrating through the body of the target and may tamble
more than a round nose Woodleigh.

When testing the PP bullets I didn't find this but because of the PP
they are slower to open up than RN (which is to be expected and
designed for).

The reason this is known from what I saw (apart from the skin reason above)
si if you follow the wound channel I could see where the petals had cut through
the internal flesh / organs and / or nicked a rib or piece of bone
before hitting the skin and stopping.

Great photo though.
