Congratulations on your new Rifle, most factory amunition will be loaded to the pressure requirements of your 30 40 Kraig. Just like most 30 06 is loaded for the pressure required for the 1906 model 1903. You should be fine.
The Kraig Rifle as mentioned earlier was loved by Deer Hunters, it has a Silky Smooth Action, and is usually quite accurate. Remember we love pictures, on this Forum.
