I have a Sako TRG magnum action that is currently a 7mm mag. I LOVE the smoothness and tight tollerances of the action and safety. Does anyone know if McMillan makes a stock for this action? Is this a good platform for a custom long range rifle? The action is PLENTY long enough for about anything out there. My concern is the plactic bottom material. It would also need a remington "sandwich" type recoil lug. Any suggestions? Flinch
