    Jay, are you talking about the 300 RUM Federal brass that caused a stir a few months back? If so, I also would be quite interested in any report. How has it compared to the Remington brass?

    Thanks, Jon Denham

    Yes, that is the brass I am interested in hearing about. A number of people were ordering it and then the thread just died.
    I'm waiting........

    I ordered a 250 piece lot. Looks like a good bunch. The only thing I have done sofar is measure the water capacity of a few cases. I must tell you that I necked them down to .284 to fire in my factory 7 Ultra. The capacities are as followed;

    1) 112.9
    2) 112.7
    3) 113.2
    4) 113.0
    5) 113.1
    6) 112.9
    7) 113.0
    8) 113.0
    9) 113.1
    10) 112.8
    11) 112.8
    12) 112.7
    13) 113.0
    14) 112.9
    15) 112.9
    16) 112.9
    17) 113.3
    18) 113.3
    19) 113.0
    20) 112.2

    The Hi is 113.3 and the Lo is 112.2. The average is 112.935grs of H2O. It also looks like a 215 primer is used and sealed. Maybe someone else has measured wall variations.
