I had Nosler Partitions fail to do their job on Caribou in Alaska with well placed shots , that Sierra's made em fall over DRT. Went back to Sierra game kings and used match king same loads to dial in the rifle. You dont want a Caribou running away 5 miles in the snow and then stop bleeding , you want em to drop where you shoot em ! Same with elk , Moose , or Bears , especially Bears !
I'm not a fan of Barnes Bullets after trying them , but thats me being anal about accuracy and expansion.
The Old Remington RN Core-Lokts performed the Best for me in several rifles over many years , then they were discontinued.
