I have been reloading Corelokts for years in my 30-06. They are very good game killers. The major problem with Corelokts is the fact that they dont have the potential for the same accuracy as say a Hornady Interlock. It is quite common to compare several Corelokts and find the cannulars are in different spots. Sometimes they vary in length. I am convinced Remington produces these to be 1" bullets. In today's world, that is really that great and for anal individuals like myself, accuracy is paramount.
