Keep in mind that if you have a factory chamber and a factory sizing die, your results will usually be quite inferior. When you order a custom chamber reamer, and sizing die reamer, the sizing die reamer has dimensional specifications that will result is sized brass matching your chamber in all directions(assuming that you or your gunsmith did good work). When buy a die off the shelf, it has dimensions that designed to allow a sized case to fit in any production rifle’s chamber without causing resistance when closing the bolt. When you setup your die to bump the should .001”-.002”, the rest of your case is almost certainly quite a bit undersized.
