I dont know if you hit the deer or not, Next time, Dont take a shot at another deer, unless your 110% sure you missed the first one. For all you know, you may have 2 wounded/dead deer out there.

Best thing to do is, Get back out there in the morning, and even if you dont find blood, cover the area with a fine toothed comb. look near water sources look for anything that might be an indication of a wounded animal. If you spend all day looking for those deer, your doing the right thing.

First thing in the morning, go right to where you herd the noises, that will be a good place to start. If you do find one, be sure to keep looking for the other just in case. And wouldnt be a bad idea to do some more practicing yardages before you attempt it again.

Good Luck. And let us know if you find anything.
