Thanks!
I am not sure what the max is but I have been as high as 28.5 grains with the 123 AMAX without significant pressure signs. My black hole barrels favorite load is 28.3 grains with the 123 AMAX and now 123 ELD. I would start at 27.0 grains and work your way up to be safe.
Edit. Its also important to note you will start to compress the powder around 27.7 grains. So you will hear a crunch as you load the bullet.
