I am with Bill, your groups with the 210 are pretty good, but dialing the seating depth a little won't hurt.
I am a 3" high at 100 yard kinda guy. Usually a 250-300 yard zero. I don't worry about over shooting elk for the most part. I have been zeroing that way for a long time and it works for me as I try to always hold in the lower 3rd of the chest.. A couple of inches on an elk isn't too bad.. Now, being you won't be shooting real far in your deer country, the 200 yard zero makes more sense.
