I feel silly about this. I had ordered 2000 rounds of 5.56 from American Gun Wrangler on 3/5/2014. It was shipped 3/14/2014 and arrived on 3/20/2014. It required a signature and I wasn't going to be able to get home so I authorized the UPS guy to leave it. Keep in mind that the UPS guy comes to my house multiple times a week and is a great guy that usually leaves dog treats for my dog etc.
This is the first time I have ordered bulk ammo and when it arrived it came in 3 boxes all taped with that strong reinforced tape (I had to cut with a knife) around all directions of the boxes. 1 box had my free t-shirt. and the other 2 contained the rounds.
Here is a pic of one of the boxes I opened and the rounds look very nice

I ordered a bunch of ammo cases from Berry's and went to put them in today and thats when I noticed each box was only 500 rounds......

This is the first time I have ordered bulk ammo and I didn't count the box when it arrived. I contacted American Gun Wrangler to see if they have records but I suspect they will say they shipped all the rounds. The UPS tracking said the entire weight was 60 lbs but on one of the boxes I can see it was 13lbs so 4 would be close to 60.
I did contact my credit card company and they said I can dispute it and they will have their investigators check it out but I have never had to do this and not sure what they can do. I am holding off to give the ammo folks a chance to respond.
The good news is that I got it for a great deal $329 per 1000 plus shipping so it's just an expensive mistake and I learned what 500 rounds of ammo should take up in a box and to always count it. Do you folks usually open the boxes before the UPS guys to count this? I think I would have been in the same boat regardless?
Feeling noobish
