    Noticed this while inspecting My brass after a trip through the Tumbler. I only have three firings on this Brass, guess I'll be discarding the lot and Parking the lapua until I can get some lapua Brass ordered.

    Is this due to excessive Headspace? Or excessive chamber pressures?

    Either of those reasons could explain your result. What's the load data? I would at first glance suspect excessive pressure.

    That should be a reasonable load. Adjust your die to just barely bump the shoulder. I'd start with fresh brass and recycle the rest of what you have there. YMMV

    Yep, oversizing and thin brass. What dies?

    I use The RCBS two die set Jeff, looking back at the issue I've had in the past I am to blame. When I was dealing with chambering issues I kept bumping and bumping the shoudler back. Well come to find out it was a pic rail screw that was causing the bolt closure issues and after resolving that I never adjusted My die depth (Damn rookie). I have crimped all My brass and discareded it since finding the head seperation since I found several with thin spots and one had a split about 5/8" long running parallel between the web and shoulder. I am going to order Lapua brass from here on out, My buddy who is an experienced handloader is going to help Me get set up right and I plan on annealing between every firing in the future as well. It bums Me out cause I have finally found a load that it likes to shoot and groups well with but I'd rather take the time to get safe rather than blow My face off.

    You are smart by tossing that brass. Aint worth the chance of a scored chamber either. You will be ok and it might shoot even better in brass as good as Lapua. You caught it in time, all is good.

    My Girlfriend was looking at pic's online of catostrophic failures with rifles/brass and She was in tears after seeing the results. I was a little uneasy after I found the bad brass but I'm here to shoot another day.

    You seem like a rational person. So consider a mistake as raising the probability of other mistakes -that you don't know about yet.
    I suggest you pick up [ame="http://www.amazon.com/Handloading-Competition-Making-Target-Bigger/dp/096269259X?tag=duckduckgo-d-20"]Amazon.com: Handloading for Competition Making the Target Bigger.

    You probably won't put it down once you start reading it.

    Great suggestion. I have lost track of how many hand loading manual and books I have. And I still use most of them once in a while for a reference.
