This is not a sacrificial collar that only does round style receivers. It is a jig that works on round, square, flat bottom-round top, long, and short. To date all Remington bolt actions, long and short. Winchester long and short. Sako I mean all of them. Savage long and short. Brno, Marlin, Weatherby, Ruger M77, and the list keeps growing. The one that has not worked yet is a Ruger MK II 77 with the investment cast trigger hanger.
