I shared a hunt O'Conner in the early 60s . We had a big Swed as a guide named Bror, out of Orifino. At the time Jack was shooting a .280 and the two of them would argue a good part of the night away on the merits of different calibers. All I took away from that hunt was O'Conner could cuss like a sailer.
I don't think the two of them ever did agree on what was the best all around round for state side hunting, but I did learn some new words!!
