    About how much does a 40 inch flat head weight from the Mississippi river weight?

    Probably a hair more than the 35″ cat shown in the picture. Need the girth measurement too for a half decent guestimate.

    I would go with 25 pounds + or – 3.

    Since you caught it, it’s anything you want it to be. Fun catch I bet!

    Got one the other day that was 42″x26″. Calculated 35.5 pounds. I’m gonna guess your (+/- 35″) was probable between 20 and 25 pounds. Get a girth measurement with that length and use this formula…(Girth x Girth) x length divided by 800. This is an IGA formula so it’s gonna be pretty close. Give answer in whole pounds. Nice flattie.
