I treated myself to a new addition just prior to Christmas and he weighed 110 grams. I just weighed him to check and he is 185 now. I do not power feed. None of our snakes are fed regularly on a schedule. They are feed when they are active for 2 nights in a row. I would suggest you might be feeding items smaller than he can manage. We are using rat pups.

Hope that gives a decent comparison for you.
