Hello Gentlemen,

I would like to know if someone knows what the G-1 or G-7 on these Bullets.
Hornady 30 caliber 180gr
BTHP NATIONAL MATCH
I've called Hornady and was unable too locate any information. These were made 1996, i have 10 boxs all with same lot # 96-101 item # 30711. These bullets shoot very excellent in my 308 26" Krieger barrel at approximately 2700 fps with ES 12 on average. Any information will be Greatly Appreciated .
Respectfully

My old manual only has the 168gr National Match with a G1 bc of .450.
The 190 match is .530.
I'd venture to say they're probably right around .500
