    Case Separation

    I owe everyone an apology for wasting your time. I did measure the shoulder bump for a batch I loaded today and one I loaded a few days ago. No problem. I just remembered I had a batch from two weeks ago and so I measured the bump. The numbers were all over the place and would certainly...

    Case Separation

    Just in case I have used my Redding S bushing dive for 25 cases I am processing and a new Forster bushing die for the second 25. Should eliminate the effects of a particular die.

    Case Separation

    Case Separation Bump is measured with a Sinclair Comparator. I only use Lapua brass although that doesn't guarantee the brass is identical--same batch. I am only using Varget through this whole process. Actually the same can. The separation occurred half way between the head and the...

    Case Separation

    I didn't think pushing the shoulder back .002" was a problem. On the current batch I am trimming to 1.760" brass OAL which on my Wilson go/no go gauge shows between low and high markers. I haven't tested any of my changes so I will have to wait until Wednesday when I go to the range. On...

    Case Separation

    Case Separation 16 times was a bit too much. I am bumping back about .002". My primers indicate 'possible' over-pressure but I don't know where it is coming from since the measured velocity of 1,750 is not high.

    Case Separation

    Last Wednesday I had a case separate about half way up the case. It left the top half of the case in the barrel. I was able to remove the case using a chamber brush. I had been noticing a faint circle around some of my cases but the circle was smooth inside and out. The batch had been fired...

    My first post. I spend most of my time reloading, shooting targets once a week, customizing my AR15 and Remington 700, and doing research on the internet. This is the only firearms related forum I am a member of. The rest are related to WWII maps and aerial photos. My web site...
