[QUOTE="misterc01, post: 1993089, member: 109160"] I was shooting last weekend, and I had three cases split( one neck, two near the base) when fired. I was using Federal GMM .308 cases with Sierra 168g TMKs with 43.5g IMR4064). They were on their third reload with no pressure or other problem signs on examination (bent paperclip, neck thickness, discolorations, etc.) when initially prepping them. Thoughts on why they are splitting? I started to replace the cases with once-fired Winchester cases, but all the necks on them seem to have a thickness varyiation from .013 - .015. inches, so not sure I want to try and turn the necks any thinner than .013. Thinking I might be better off just chucking them all (about 150 cases) and just get some Lapua or Perterson and start over. Suggestions? [/QUOTE]
