In any case 308's are easy peasy.
Yep.
Last Sunday I did a 100 yard test with three lots of RL15. The rifle was a Kimber LPT fitted with a Leupold VX-3 6.5-20x40LR set to 14x. The target was a half inch dot on a grid background.
Load: FC brass, F210M, 168 CC Nosler at 3.225" length in a Sinclair nut, 2.81" nom. OACL
Powder was dispensed from a Redding BR-30 measure set to throw 42 grains of the reference lot of RL15. The other two lots threw 40.7 and 42.4 grains on the same setting, and that's how they were used.
The first three targets were shot in round robin fashion, load A on target A, load B on target B, ... until fifteen rounds were fired. After the rifle cooled, a fourth target was shot with six rounds. Two of each of the three loads were fired, abc, abc.
I overlaid the four targets with a light behind them, and the resulting composite 21 shot group is 0.92" center to center.
No doubt, it's eager to please.
