By the way the Sniper Match Accuracy .308 load developed at Marksmanship Training Unit Armory loading room is.....same brass, same primer, same bullet...but uses 41.5 grains of IMR-4895 for 2,600 fps. Used in both M-14 and Remington 40X Rifles.

They have a production milling machine that turns out Stainless Steel Douglas barrels with 1-12" twist profiled and ready for building. Each one is air gauged by one man, and any minute issues, it immediately goes in the trash can...broke my heart to see that!

So, both powders work very well, but 41.5 IMR 4895 is their favorite.....2.800 OAL, they were using Federal Brass when I was there, but Lapua is probably a bit better if you can afford it...the Federal 210 BR primer is the finest in the world.

Copying the Fed Prem GM factory rounds....

New Lapua brass neck sized then expanded, Hornady 168 Amax, Fiocci LR primers, 43.5gn ADI 2208 which is just about the same as Varget or 4895, Hardy 30" 5 land barrel in a H&H millennium action, 2 sighters and 10 for record at 600yds - slight breeze from L to R....60.3, those are 1 minute squares on the target face.

I was reasonably happy with that..... ;)

I have been using the .308 in a Ruger K77VT for going on 20 years and
I use IMR 3031 at 40.5 grains with a CCi large rifle magnum primer and
a Sierra 168 grain HPBT match bullet. In that rifle, I can shoot .5 MOA
with this round and it shoots 4 - 6" at 650 yards. I have tried
4064 but the 3031 load was slightly more accurate. IMR 3031 is not
generally used for the .308, but for me it works great. What is
funny is that I also shoot a Savage model 10 tactical in .260 Remington
and that round likes the slow IMR 4831 behind a 140 gr Sierra HPBT match
bullet. The .260 is just a necked down .308 but it loves that slower
4831 powder.
