John, your experience mirrors mine. I took my biggest whitetail (4pt, 200 lbs dressed weight) with a 150 gr. Hotcore from an 18.5” 308 carbine, and my biggest bull elk (mature 7x7) with the 165 Hotcore from a 22” bbl’d 308. Both bullets on each animal exited. When I used to shoot bullets into test media, I was always impressed at how well the 30 cal Hotcore’s performed, and came to think of them as “the poor man’s Partition!”
