The number of people I've hunted with is limited, but when I stop to think about it, I don't know anyone that actually hunts with a centerfire rifle using the original barrel-mounted leaf/notch/buckhorn sight. Savage, winchester, marlin, browning lever guns; Rem autos or pumps; and any bolt actions, whatever - if they use iron sights they have a receiver mounted peep, mostly Redfields or Williams.
Those that have left the original sight on are actually using scopes. Except do recall one cousin with an old tip-off (Weaver?) scope base on his Win 94, he may still have the barrel mounted open sight that gets used.
