Ruger American Rifle .308 22” barrel 1 in 10 in twist.

I have seen Ruger American's do similar things and at further distance.
It seems like they have it figured out.

I would agree, but with mine it's better at closer distance, like 100 yards! Might have something to do with my aging eyes.

Don't have a 308, but my adult son has a 6.5 cm Ruger American and I have a 243 Ruger American for a truck gun, both are very accurate for inexpensive rifles. I've never shot factory loads through mine, but my son's shot slow with factory ammo, so I worked up a load for him with 120g BT'S. Good velocity and very accurate. I wouldn't have believed this was 200 yards had I not been watching through my spotting scope.

That’s outstanding!
I’ve heard from friends and have seen similar results from StaBall powder, especially in the compact and highly efficient cases like the 6.5CM and hopefully the .308 as well.
