Greetings,
From my testing in the .308 the ADI powders, including AR2208 seemed to shoot a bit better than IMR4064 at lower pressure and AR2208 looks the best of the bunch from your results. One thing you could consider though is a better target. These days I mostly use the NZDA 50 and 100 metre targets but you can make up a hollow square target with red tape on paper. I just quarter the inside of the circle or square with the cross hairs and find this more accurate than trying to aim at a fine point.
Regards Grandpamac.
