I spend half of my life travelling so always looking for recommendations, to date I have found:
UK - for shotgun shooting the GunsOnPegs ones are OK, BASC one just....OK. As above The Outdoor Gibbon and The DeerCast
International - Into The Wilderness - Byron Pace, very UK heavy recently but for UK the Sam Thompson ones are worth a listen
US - there is some good episodes on The Big Game Hunting Podcast esp the Copper one and for Africa the Kevin Roberston episodes. Some of the cartridge comparisons are interesting and plenty of US hunting stories. The Hunting Collective OK in parts
Finally, for books get the BorrowBox app and use your library card to get audiobooks for free, lots of titles on there, recently listened to Jake Fiennes' Healing the Land, he's an ex Gamekeeper
