Here are some of my results from my 1-17” twist Krieger barrel Remington 700 .308 Win. The rifle wears a Remington SPS Varmint stock and the barrel is neither bedded nor free floated. The chamber is a saami spec .308 Win throated for my load.:

This is shots 11-20 from this barrel ever. The load is the NOE 30 XCB over 44.2 gr. RL22 in Hornady Match brass with WLR primers. This was fired at 50 yards after shots 1-10 were used getting on paper.

This was at 100 yards. The only difference here is BR2 primers.

Also 100 yards. These shots were fired in less than one minute. The flyer at upper left was shot number 2.
These loads have been chronographed at ~2430 fps from my 1-12” twist rifle. As this was the initial firing of this new rifle chronographing was not done, nor were bullets sorted other than cursory visual sorting at time of casting. These bullets were air cooled but have aged about 2 months since sizing and lube. Lube is 2700+
