    Several of our group had problems with pierced primers using CCI. We change to ww primers and problem went away for now. Between us all we had not had a problem with CCI till then. Figured their act had slipped for awhile.

    Again...not having a 500...I would think a slower powder with that heavy boolit might help. Try HS-6 or Accurate #5. It could be with the faster powder you have a very high initial pressure spike trying to get that monster moving down the barrel.

    HS-6 is a faster powder than Bluedot. Also you can see in his pictures that all loads are consistent.

    I would trust HS6 more than Blue Dot as the latter can be streaky. With HS6 you just adjust the charge and there you have it.

    Quit fretting about climate change. Itís how much stronger gravity is getting every day that is bothering me!
