[QUOTE="MagnumManiac, post: 2047229, member: 10755"] Lapua cases are NOT drilled. No case on the planet is drilled to make the flash hole, they are all punched. Period. Ask Lapua directly, email them, they will tell you they do not drill flash holes. Consistent brass comes down to the process of making it. All brass cases are either drawn in many dies, or extruded in fewer steps. These two processes are different, one, extrusion, is more precise. Drawing always makes one side of a case thicker. A case is good when it is hard enough in the head to withstand many firings and become stable, which means it has work hardened enough that several firings no longer make the case grow outward. Annealing the neck after every firing is also the key. Cheers. [/QUOTE]
