I am getting parts together for a new hunting rifle build. I'm going with a Stiller tac300 action (long action so I can seat bullets at what ever depth I want) and Kreiger barrel chambered in 300WSM sitting in a manners MCS-T. Since this is going to be a hunting rifle, I want to go with an internal mag. I have found Pacific Tool and Guage bottom metal, but I wondered if anyone has any input as far as if I should go with factory remington box, spring and follower or maybe a wyatt's internal box and the rest factory or some other route that I dont know about. Any help appreciated.
