That may be true about the regular core lokts which i still believe are good bulletts but until youve shot something with the new core lokt ultras you cant say a thing about em till you try em. They worked better than the noslers that ive recoverd. These ultras mushroomed perfectly going through bone. One went through the ham, traveled length through the body went through a shoulder and was stuck in the hide. I will take a pic of two i recoverd and post a pic. I think they have a good bullett in the core lokt ultra. Im not impressed with noslers at all after shooting these. But to each his own, i dont pay 1000 to 4000 to hunt elk so i dont have to worry about that.
