I don't know that one is really my favorite but I am particial to 6.5's and 7mm's. Going to Montana bird hunting in Oct, not sure where as I'm going with a friend. East of Great Falls I think. He told me to bring a rifle as for another $35 we could also get a doe antelope tag. Thought about my 25-06 but the 6.5x55 is winning out. Mod 70 featherweight w/2-7 Redfield, one of the new Redfields. This rifle really grow's on ya. Handles a lot like my old Rem 660 and I loved that rifle. Unfortunally, so did my son!
Let me start off by saying I am not a farmer.
I am a deer hunter and I do own a tractor and have all of the equipment - but that does not make you a farmer any more than standing in the garage makes you a car - well, you get the picture!
Having said that - and with most of my ineptitude fairly well hidden - I do think that buckwheat is one of the most under rated cover crops out there.
I say cover crop because I see mixed results as it relates to the deer eating the plants.
