Sorry mate in the US it's cheaper if you buy in quantity, 5.45x39 comes in 1080 to a can, 2 cans to the crate. 7.62x39 is usually 1000 round pack, 50 boxes of 20. Handgun ammo I used to buy in 500 or 1000 round lots, 10 or 20 boxes of 50. I could easily go through 1000 rounds in a day at the range. .22 comes in 500 round bricks or 2500 round buckets.
Do you buy your spirits in shorts or do you save money by buying a bottle at the supermarket?
