hi the land sounds good i would set on the edge of the woods over looking the feild. the 223 would be the best for saving the pelt but the 280 would have more range. ether one would work just fine if you can hit you target. i would use wich ever i could shoot the best with. as for calls it is up to you i wish i had a electric call but you can get by with what ever as long as you practice with it. good luck!
