^^^ Right there.
The more common problem seems to be feeding undersized prey. This doesn't stretch the jaw correctly for the snake.
If it went in then it should come out.
May I ask what temp.'s you have the tank/tub set at? And, if you have a hide on both the warm and cool side (When my BP's get 15-17% body weight prey they hang out in the warm hide much more, with 10-12% body weight prey they are mostly on the cool side).
Oh, I've also noticed that larger meals seem to result in longer digestion periods and eventually a massive deuce.
