I have to disagree with some of you. Although there are many bullets that are better than core-lokts, the fact that the core lokt bullets take more game every year than all other bullets combined must mean something. I have never had a deer go more than 25 yards with my .270 with 130 grain core-lokts. But I had some deer go 100 yards with a 30-30 with core lokts, and some fall imediately.
