In Handloading For Precision, the author offered this opinion: "Without going to extremes, weighing cases is the single most important thing you can do to improve performance in handloads. Deburring primer pockets in cases is helpful as well." Weighing cases ensures the interior volume of the case has the potential to be the same from case to case, which in turns provides the potential for the each case to produce identical pressure and velocity at each firing. Prior to fireforming, there are a couple things we can do to help ignition and promote consistent release of the bullet. There are many good dies on the market, one example being Redding`s Competition die set with a body die. Once set up correctly, run each case into the full-length sizing die. This ensures each case is identical in length and size from the head to the shoulder/body juncture and from there to the shoulder/neck juncture. Now trim each case to the same length. Chamfer the case neck inside and out. Cases should now be identical, one to the other, as is possible
