Just got a surprisingly cheap .700 round for display(no powder or primer). I noticed in the 12 gauge from hell thread that Ed Hubel said people should consider enlarging NE pockets to take BMG primers-someone else must agree. My case is headstamped HH (Hulsen Horneber) and looks to take the big primer. The .600 round I bought a couple years ago had a pocket that accepted a dummied Winchester Large Rifle(anvil and priming compound physically removed)-Does the .700 take a larger primer anyway, or is this more likely to be a recent development?
