NCOutdoors. I hunt elk with the Nosler Partition. Just about everyone in our camp use premium bullets.

The Oct 2002 Shooting Times had an excellent article on premium bullet performance that contains numerous graphs chronicling the bulets' perfomance. It is well done.

The Core Lokt is a well tested bullet with great reputation. It may not be the best bullet for big thicker skinned animals.

I also reload Nosler Partitions for both hunting and a small amount of zero verification.
Just recently read an article on the new Core Lokt Ultra but am having a senior moment in trying recall which magazine. Article was favorable.
Regards.
