Opal ---If you are starting down the accuracy road, I would recommend a Type S Redding FL die with a couple of bushings..probably a 334 and 335 for use with Lapua brass. For seating, go with a Wilson inline with a micrometer top. And, it never hurts to outside turn necks to insure consistent wall thickness.
By choosing the correct freebore when doing a build, it is pretty easy to select a bullet that will seat the bearing surface/boat tail forward of the donut thereby eliminating that issue.
