You don't go to gun shows and/or shop online to buy in bulk...?!
( just curious...not trying to put you on the spot my friend... )
I myself go to guns shows in Pennsylvania every time one is within driving distance to
add to my stockpile...just recently add a case of 5.56 and 7.62 the Saturday before Veterans Day 2012...
$230 for Wolf 5.56 and $200 for Wolf 7.62...( tax included )
