I will add 2 things.
1. He talks about parkers kicking hard, even with modern ammo in my parkers they seem to kick about like an 1100. Certainly nothing like my father's 20 gauge browning A5s.
2. He was very complimentary of parkers, this was basically the criticism.
Last thing I think I found a pic of the hunter to whom he refers.
With all love and admiration to you Destry
