Tough choice, I would lean toward the Burris mostly because of the ballistic plex reticle being available. However Nikon has a new reticle that rivals the ballistic plex out this year. Price/Quality points on both should be similar.
I don't know either scope but consider eye relief when scoping a magnum caliber. Longer eye relief for the recoil. Most quality scopes have this covered already.
Nothing like a cut eyebrow if you have to get too close to see well.
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.
