All the ones listed so far
Great stuff out there, and some real good information. I really enjoy meateater because the range of topics is very broad. Lots of content goes deeper than just "how to" or stories I enjoy that.
HuntHarvestHealth is probably my current favorite another one that is great because the topics dive into more than just hunting. If your into living cleaner, family health, and tough hunts its a must listen! This was my first year going MHF ( mountain house free ) and the ideas from this podcast were key to taking the plunge. While I am still refining my own system its been great getting the ball rolling. If you have a significant other they may also enjoy the listen and comparing notes.
I am a gear junky and kifaru cast is a no brainer in that department.
TRO, GB, etc.... I enjoy them, but find myself picking and choosing the episodes. Kinda reminds me of the "old" days and getting magazines. Certain articles got read right away based on content or author others were left for later or glossed over completley.
Elk calling is obviously a hot topic in all hunting arenas. And lots of great information! But I have found myself shying away more and more from "how to" anything in that realm. Not because I think anyone is wrong, but simply because for me it is so situation and animal specific that it has gotten confusing trying all the different "theories" that are thrown around as sure fire ways to bring in a hot bull. I prefer guys that share it in a more of this is what I do/did, and it worked for me.
