They weren't Corelokts but I shot a bear in Newfoundland with 220 grain roundnose Hornady Interlocks once. Perfect broadside, double lung shot. It went 6 or 7 yards and fell right over. A 220 is plenty for bear.
I just bought another box of those 220 Interlocks and that is what I'm loading for bear season this year myself. Best of luck.
My Dad killed 5 bear largest being a 383 lber in PA and 4 in Quebec all with 30-06 180 RN Corelokts. Not one offered up any refusal with all either dropping in their tracks or down within 25 yds. That 220 should be more than enuff assuming a good hit.
Great load and gun for driving bear. If recoil is too much for ya, drop down to 180's. Still plenty energy to part the laurel!! Double lunged 240 pounder at 160yds with 140 grain hollowpoint and didn't go anywhere. Complete pass thru. But he was just munching on acorns, I think yours will be moving quited rapidly!
