So after premium is defined we gotta ask the question, before the Nosler Partition showed up did hunters shoot and kill elk every season? I remember the two most respected bullets in Alaska by the guides and hard core hunters I met as a kid in the 60's were the Nosler Partitions and the "old style" Core-Lokt bullets. I wonder how much "bullet failure" was poor shot placement for a variety of reasons, or poor bullet selection for the chosen animal.
