And i did the same as joel, 1/2 grain of lube per 1000 cleaned jackets. You won't stick a seated jacket in the die, there is a full size punch ejecting it. I did add some lube and tumble again for pointup. That need to come out easily.
    ferris pindel put on a show at harts rage on how to core seat when mark showed on the outside of the jacket from punch pressure that was what you used . Lightly

    George,that is what I am getting on these .925 30’s about 2/3 way up the jacket. Some are really good, some not so good.

    i put cloth in small cookie tray put about 200 at time.this generaly left enough to point up with. After pointing up i rolled on paper towel this keep barrel from copering up.

    r on the jacket may be due to being pushed off.

    Jackie, Around Feb my house goes, really dry....25%. And I was getting cases stuck to punch. And stuck in the point up die. Got a pic of my thumb trying to wrestle a press. Perfect 6mm hole through my Thumb nail.
    Called George. I was using his formula of 50% lanolin and 50% Vasoline...
    I switched to lanolin and castor oil. Works great.
    It was a couple of calls to Lowell Hottenstein and George Ulrich. To figure this out.....

    On the topic of imbalance and or dispersion:

    I have read about issues with jacket wall thickness, possible air pockets between jacket and core and core movement during point up but, as to core uniformity other than Vaughn I have not heard any concerns. Just wondering about miss distance values and flyers coming from the lack of core homogeneity and or uniformity? Is this in the - being to anal – category?

    the question of too much bleed by has not been proven to hurt acuary the tests i made and doc. Matretzos xray. Prove4d that.

    Yep.
    You squish that lead and stretch that jacket .005-.008", that lead ain't going no where. And it is shaped by the jacket and Core seat die.
    I have cut the jacket off some. Chucked up the bullet in a drill and used a hack saw to cut with. And had to use 2 pair of vise grips to pry the jacket off. Vise grips against each other....
    I am sure eventually, there might be some oxidation to form a bond....That might take years. Or maybe not. there may not be enough O2 to start that....
    And most BR bullets are not around very long.....

    To clarify my poorly worded question: Have any bullet makers associated any relation between bullet imbalance and the Quality of the lead wire? - Homogeneous make up and purity.
