I bought a rifle barrel liner for a Remington hammer gun and it's marked 10ga 40- 2 1/2. I need some 40-65 or 40-70 cases. If anyone would have a couple they'd be willing to part with give me a email at bladesmith46#hotmail.com I'd really like to shoot it once it gets back from Bachelder who is fitting it and redoing the Damascus barrels. Thanks Paul
