If you want to be paranoid worry about the rumors the Government is keeping track of bulk ammo purchases through the credit card companies. Personally though I've had three cases of 7.62x54 delivered in as many months with no problems, signatures or even ORM-D labels on the last two. I figure if being a Veteran, NRA Life Member, C&R holder, active in my church, active on several shooting or firearms related web sites and occasionally voting for Third Party candidates has not got me on some Government watch list then ordering ammo online is not going to be enough to tip the scale.
