Thread: 18 inch 308 powder

Hi there
Currently using ADI 2208 in my 18inch 308 with 168gn pills. Getting around 2550-2600 fps. Get about 2780 when I use 125gn hornadys (wallaby load)
Is there another ADI powder that would be more efficient in a shorter barrel?
Currently use 2208 in both 308 and 223 loads so would be great to use one powder across the board but happy to split.
223 is a 19 inch T3x using 75gn Hornadys.

Appreciate any feedback.

Cheers
