I've only shot two fallow does with mine using the Sierra 130gn Gamechanger with 43.5gn H4350. Both bullets exited the deer.
The best groups I've shot have been with factory Hornady Whitetail 129gn SP. My handloads with the same Hornady 129gn bullet have been just a tad larger, about 1/2 inch. The Gamechangers group into about 3/4 inch but I haven't bothered to adjust seating depth to try to better it.
