I have hunted birds a good bit of my life Dove Quail Pigeon, thiswaa before the screw in chokes and the barrel lenght's in those days were 26 and 28 30 if you have a 3 inch mag. was never a need for the 3 inch as we could use lead shot in those days. Now the norn is non lead shot. I am thinking your not going to do well with the really short barrel. And as you said the price of a new barrel a man can get another shotgun.
The other day this pasted week I picted up a Stoerger turkey gun used but not much for $240.00 out the door the price of a new barrel and its a 3 1/2 too boot with 2 chokes.
Been looking at the guided hunts as that seems to be the only way my pal and I are going to be able to hunt geese. I guess the 26 inch barrel would be nicer to have but I have uses for them as yote guns and turkey guns , and will do more of that type of hunting than I will goose hunting. How ever if I do get the fever I'll either get longer barrels for the shotguns or I'll get new shotguns just for goose hunting.
The place I checked out for the guided hunt said they had shotguns to rent and the shells for you to buy. I know it would be a pretty high price but would be cheaper thn a new barrel. nyhow I am going to contact them and see what they say about the 24 inch barrel lenght. If yhey feel is not good idea then I'll rent the shotguns from them just to see if I like that type and style of hunting. Hope this helps you.
