One challenge I used to have was thinking a core always has to stay with the jacket to do its job. Opinions on this subject will always vary but the fact still remains, your game died and unless the bullet vaporized it seems to have done its job. If you want to see carnage try the Nosler BTH or Sierra GK. You can fit a soft ball through the wound track with them. But still they bring the game down.
Hornady SSTs give similar results in our experience. The Interbond however is a different beast with a bit thicker shank and perhaps a harder core. Great bullet with a high BC but too rich for my blood.
Been using the big red H products for a long time and will agree the cores do shed from time to time, mainly in the Spire point design. Round nose hold up very different in my experience. Off the top of my head:
.308" 165gr SP out of an 06 thru the head of a whitetail at 200+yds hit just below and behind the eye left the entire jacket under the thin hide on the off side. This would be around `95 or so.
Yet this year I made a near identical shot on my whitetail but at 80-90yds with a .257" 117gr RN and it went straight thru leaving no sign of lead or jacket that I could find and I looked hard. Same load on a doe at 80yds broadside thru both lungs and exited.
.338 250gr RNs out of a 338-06, one into a bear at 35yds in the neck on entry and thru the vitals stopping in the hide offside in a perfect musroom.
Second into a Bull moose at 180 yds, stopped under the hide with the same result.
7mm 154gr SPs went into my wife's elk at 150yds, thru both shoulders and held their cores except one that was just the core found.
Same load for my bull at 360 some yds was a double lung and exited while the second hit the shoulder quartering towards me, and clipped the spine then stopped between the ribs on the offside, it was barely holding the core but if you saw what it went thru you wouldn't blame it either.
Perhaps I should get out the recovered bullets box and snap a pic or two.
Depending on the calibre I am shooting (weight availability) they are my go to brand.
