You just made me remember a story about Jeff boondocking in Mexico, carrying a 1911 in .38 Super, because .45 was verboten there. Some large bird flew over, and he shot it with his 1911, which featured notably in a chapter of one of his books.
In the Gunsite rifle class, we shot moving clay pigeons with our .308 bolt rifles. Also did that at his Whittington reunions. My proudest rifle moment was breaking two successive clay pigeons with Finn Aagard’s Mauser .30-06.
Despite his later displeasure with IPSC, Jeff was one of the original gamers, and loved technical shooting challenges.
