Swampman,
I did the samething a few years ago for my Mod 1100 Rem 12 Ga. It had a 28" modified barrel on it. Originally it was used for early fall squirrel hunting in N.W. Louisiana and E.Texas, along with duck and quail. I put a 26" ribbed barrel on it with Remchokes. It appeared to be faster on quail here in Colorado but on pheasants for some reason kinda of yearned for the 28" barrel. But for quail it is hard to beat!
