Why even use a partition or core-lokt on thin skin animals like deer or even black bear? I don't understand that... Pointed soft points work in every situation on deer and black bear with a .308. 150-170 grain soft point and shoot. Friends of mine shot controled expansion bullets for years at North Dakota Whitetail. We got tired of blood trailing deer. The bullets tended to enter and exit without causing the damage a soft point would. They finally quit wasting there money on expensive ammo and started dropping deer where they stood.
