We gave it the old college try but it just wasn't doable with that gun. Nice gun though. I shot sporting clays with one last year in Canada. I liked it but I don't think it liked the ammo that was furnished. It didn't cycle reliably. I don't think that's indicative of the gun.
Drilling and tapping may be the way to go with that one. I like that setup a bit better than the speedbead if you are doing mostly just turkey hunting with it.
