[QUOTE="Tac-O, post: 3018640, member: 109994"] Darn. If this is due to brittle brass and being an annealing issue while drawing.... I'd bet that this issue exists to some degree throughout my entire box. It was not cheap and i didn't buy it through Lapua or one of their dealers. To answer a couple of the questions above: I annealed before necking these up in an induction annealer to the point that they just start to glow, about 6.8 seconds (Peterson takes only 4.8!!!) Diameter... At which point? The virgin shoulder is about 0.471-0.472... can't remember. My chamber is 0.4865 at shoulder and I'm also moving it to 40*. Head diameter at the edge of the extractor groove on virgin is 0.499- and on these cases that split it's 0.499. I'll definitely contact Lapua to see if they'll inspect them if I send them in. I want to know if it's a brass defect for sure and if I should just abandon the rest of this box of brass. I don't want to damage my chamber or end up with an injury. I'm wondering if I should avoid shooting the ones I've already fired. I've got 25 that are on their 2nd firing. Either I'm a glutton for punishment, or it's not that much trouble ;) it's shot really well and I enjoy it. The only real issue I've found is that either my sizing die swells around the base on Peterson cases that have at least a few firings (causing the clicker issue) or the die is out of spec. The die kinda sucks and wasn't hardened. Anyhow, I've got up to 11 or 12 firings on Peterson with my 2825fps 185 juggernaut load, no donut issues, and the pockets are still tight. That load is very very accurate. Someone who knows what they're doing needs to pick this cartridge up and play with it! [/QUOTE]
