More on O'Conner

One thing that i think O'Conner can be criticized for his failure to distinguish between premium and conventional bullets. He was an early adopter of Nosler Partitions and they obviously served him well. However, in his writing, he tended to lump these premium handloads with conventional commercial rounds.

There is a big difference in performance between a 130 grain Partition and 130 grain Silvertip. Yet i am sure that thousands of people took to the field with the Winchester round and wondered why they couldn't duplicate J O'C's results on elk or moose.
