Interesting that it's not .308Win.
Haven't seen commercial 7.62x51 ammo for a long time. Coincidentally I have just been reloading some Lapua brass headstamped 7.62x51, from ammo originally purchased from the NRA in the early 90s I think.

Re: GGG 'Imperial' First Look
The GGG was set to produce NATO standard ammunition for their armed forces so their case forming machines will be designed to make 7.62 x 51 not .308 Winchester.

Just back from an exhausting session at the range. Part 2 has some more info, and includes chronographic comparison with RUAG.Dannywayoflife wrote:Interesting please let us know how it shoots!

Re: GGG 'Imperial' First Look
Very interesting thanks.
I tried some on Sunday - I don't shoot as well as yourself, but I shot a respectable (for me) 48 at 600...and taking my wind reading errors out of it I thought it grouped nicely.

Re: GGG 'Imperial' First Look
Now with RUAG dimensions for comparison, and relative jump.
