GGG 0.223 box codes

[Dunc]

My normal 0.223 ammo is GGG 62gr and the box top code is 010-GGG-15. I normally buy from the NRA and my scope turrets are calibrated for this round.

 

However, I have just seen a box in my ammo safe with the following code; 330-GGG-13.

 

Can anyone please tell me what this code means? I guess that the last 2 digits could be year of manufacture but I'm asking in case the 330 code could be for a different bullet weight as I believe they also offer 55 gr rounds in 223.

 

Any advice would be much appreciated.

 

Thanks in advance.

It's the same stuff, just a different batch number

Don't worry about it

Thanks Mark, just wanted to check I didn't have a box of 55 gr.....
