What's a "check card?" Would a credit card that you put money onto it for a single use work for an international transaction like this? If I was ordering bullets for an AR-type rifle, I'd want to be dam-ned sure they were 0.224" in diameter versus the 0.220" used by the AK-74.Might use a throw away check card. Sure as heck would not anything tied to my accounts.
You really can't. You could ask but then, the outfit might be one that will tell you whatever you want to hear just so they can get your American dollars into their Russian bank accounts.Do not know how you would verify the diameter before getting them.
