[QUOTE="Vettepilot, post: 2078959, member: 114372"] Yeah, you might try it with the others. The ejector is trying to jam the case forward against the shoulder, then when the firing pin hits, it too pushes the case forward. Then the case expands, and locks in place upon ignition. Case expansion/lengthening then occurs right at the point where we see head separations. With the case and chamber clean and perhaps polished up a bit, then lightly lubricated, the case is more likely not to lock into the chamber as normal, and therefore expand forward in the neck area as desired. Wildcatters and people forming cartridges sometimes use this trick. Don't do it on a full house load though, because the increased bolt thrust can hammer the gun needlessly. Vettepilot [/QUOTE]
