I've owned two with 25" tubes and still do one with 28"ers. Those short tubes don't swing or follow through on crossing shots. They are strictly for snap shots. I hated them and sold them both a few years ago. One for 650 and the other for 750. Kept the 28" gun and it is an entirely different beast. Wish they made 20's with 30" tubes. You'll probably get 12-1500 for your gun --- and it is the grouse guys who will love it. Chopper
