I didn't say he was delusional, I said he was delusional in his devotion to to the .270.
In Jack's time only the 130gr. and 150gr. bullets were available OTC. Yet, he argued to his death that the .270 was better than he .280, .30-06, 7 mag and others which were just as good or better. He and Warren Page conducted decades of pissing matches where Jack defended the .270 at every turn. He worshipped at the altar of .270. The only other cartridge he was a fan of was the 7x57 which is one of my favorites.
It is my secret contention that he didn't die from a heart attack on his Hawaiian cruise. I suspect that the other passengers got fed up with listening to his diatribes concerning the .270 and threw him overboard.
