    6.5 creedmoor: 52-53 gr case capacity
    6.5 SLR: 55-56 gr
    6.5 PRC: 66-67 gr
    6.5 SAUM: 70-71 gr

    The PRC has 25% more capacity than a creedmoor, and 5-6% less than a SAUM. In quickload, holding pressure constant at 57k psi in a 26" barrel with 140 hybrids, a 6.5 SAUM (H1000) is about 30-40 fps faster than a 6.5 PRC (H1000), and the PRC is 220 fps faster than a 6.5 creedmoor (H4350).

    Yes, I had a case of Yugo 7.62X25 ammo that every other case spit the neck and a tin of Ruski 7.62X51 that stuck every eighth to tenth round, or so, in every gun I tried. But I've never had a custom hand load show the slightest signs of pressure. I either got them out of books, of the guy who does my loading has huge experience.
