Neck bushing size is more about the brass you are going to use than the rifle they are going in. Different brands of brass have very different neck wall thickness. Assuming you are NOT turning necks you need to determine the diameter of the neck of your chosen brass with a bullet in it. Then most people will size the neck .002 to .003 smaller depending on the thickness of the brass and the tension that places on the bullet. I would probably order both.
