I have caught a 4 and 5 lb already this year but my biggest I didn't get to weigh but it was out of our farm pond and he was caught on a 6'' jerk bait and totally destroyed the lure. His mouth was so big I could put my fist in it and it would not touch the sides of his mouth. I want to say he was 6to 7 lbs when I am comparing him to the 5 lber I caught
