That's one of a number of reasons to use liquids for large boosters, >1MLbF.

I was trying to work out how you could have one "batch" mixed in multiple
mixes or something.
That makes more sense but it's still gotta be a heck of a mixer.

Just to show the importance of addressing the variability of each batch of
propellant: Note that the space shuttle required that both solid rocket
boosters be cast from the same propellant batch - they were concerned about
differential thrust if they were cast from different mixes using the same
formula!

Thanks!
Shuttle didn’t quite do that, it would have required enormous mixers…. But
they did have the same batch poured into both right and left booster
matching segments of the segmented booster. There could be variations
segment to segment but they’d be the same side to side. Thrust might vary
a bit flight to flight as long as it was right/left balanced.
