No, never tried it, RL-15 works so well with a variety of bullets I never looked any further.

i had trouble with stability past 600 yards with the 75 amaxes in a 9 twist. moved to 70 grn bergers and haven't looked back.
i also shoot varget and rl15; both produce similar velocity at 33.4 grns, and are very accurate.
