RE: 7.62X39 VS. 243 WIN. FOR DEER
I know it's not one of the options listed, but like several others have suggested, I would recommend going with something just a little bigger that can still be downloaded (spelled smaller weight bullet) so that recoil is not an issue.
Go with a 7mm-08 and load it with 120 Grn Nosler Ballistic Tips. You can get the 7mm-08 in a light short action rifle and the 120 BT's will provide a very light recoiling round that is more than adequate for deer.
