Only place for 45acp is Can Tire, and you may well be S.O.O.L. with regards to the 7.62x25 Can tire does stock some surplus ammo, but I think it is all 7.62x39 and 7.62x54R
I will take a look for you tomorrow if you want, but the .45acp is certainly not cheap there. I think it was about $31 a box average, but I'll check first on the prices. Better bring a barrel of cash with you............... pretty soon its gonna be cheaper to buy a new Norinco 1911 than a box of the ammo to shoot out of it. Walmart here still has a skeleton selection of ammo, but it is all rifle ammo, and some small amounts of .22lr and .22lr shotshells................ sucky sad looking ammo case.
