Thread: Split necks on test loads

    Split necks on test loads

    Guys been out this afternoon to zero rifle and try some test loads
    hit the jackpot with a one holer with Barnes copper in tsx in 30 .06
    problem is getting some splits on end of neck this was with max load
    do you think this sounds like a pressure problem or weak brass ?
    your thoughts please
    regards pete

    Its normally caused by hard brass how many times have they been fired, anealing would probably solve the problem, what make is the brass.

    Hi Keith
    it's some federal I think it's been fired about three times
    I hope I don't have to back off the load as it's the best group I've ever shot

    try and get a few cases of a different brand and try the same recipe regarding all the other components and see if it makes a difference. I know folk are gonna reply to what I just advised and say different cases mean different internal dimensions etc. blah blah blAH..... BUT JUST TRY IT! YOU MAY FIND YOU MIGHT NEED TO ALTER THE POWDER CHARGE BY HALF A GRAIN OR SO BUT IT'S WORTH A PUNT.

    Does annealing them add that many firings,after fl sizing usually the case needs a trim, annealing may save the necks but the bit that get trimmed of comes from somewhere, case thins just up from base then.

    Is annealing to go with neck sizing ? Ive no idea

    Neil going to trim the next batch just to eliminate any variables
    i will expect one holers with the new tac
    but was a bit surprised with an ole Blaser and my old eyes
    Regards pete
