Well the biggest I have killed here in Mo was 24lbs and weighed by the MO Conservation Dept game warden their on their digital scale. I can tell you right now that a lot of the big 26, 27, or 28lb turkeys on some of the old scales that were used to weigh them are none other than fish stories, and they continue to grow. It takes a big bird here in MO to weigh 26lbs. And yes their are some birds that will go that and maybe more. But they are pretty rare. The digital fish scales that they have now are extremely accurate and will weigh within 2oz.
And anyone that kills even a 25lb gobbler in the fall regardless of where your hunting unless of course you got a feeder that is feeding them like farm chickens I for one would like to see the bird. It takes a hell of a fall bird to even go 20lbs here in MO. That's something my buddy who has killed a ton of birds and that goes for his dad as well have told me. You just don't see very many fall birds that will keep their weight and that includes the big boys that might go 25 or 26lbs in the spring. The biggest fall bird I have ever kiilled weighed I think 18lbs 4oz.
