fx king .25 and altaros slugs

hello. finally got my altaros in the mail. was wondering if somebody knows best setting for macros and micros for king .25 600mm and altaros atp smooth 49.5 grains. I'm new whit this sorry for such a noob question.
and thanks.
Yes, 880 to 900 is a good speed for them. I have a 600mm Superior Heavy in my Panthera and it shoots the Altaros ATP Smooth 49.5 grain at 888 fps with Micro at just over 3.5. Macro doesn't matter. Reg at 135 bar.
