I love Sierra bullets for accuracy and I have shot quite a few critters with the 30 cal 180 and 165 BTSP gameking. The cores separated about half of the time so I was surprised that they stayed together for him.
Yeah these bullets have quite a high failure rate. Not even on my radar, but buy whatever you like I guess.
Only "failures" I get from em is the deer fail to live.
Yeah they separate and yeah they are hard on meat but they kill like lightning.
Been around Sierras more than any other bullets in the last 40sh years. The sumbitches flat ass kill critters.
Sure I kill deer w Partitions, Interlocks and several others but I can't see that they work a lick better than Sierras on little old whitetails.
