Mill setting

[kkimmes]

Was at my LHBS the other day to buy some grains for my next batch. I don't have a grain mill so I crush at the store.
The tell everyone that the mill is set to a gap of 0.43. I have only done 3 all grain brews so far, so I have little feedback if this will crush enough.

My question is, should I double crush or should a single run be ok?

That's not really way out there IF the mill rollers are not worn.
If you BIAB, you can go to darn near flour - like .025 or so.
If you use a more traditional MLT, the range I normally see is from .035 - .045 or so.
I have my mill at home set at .038. I get 80-85% efficiency and don't need rice hulls (but I don't make many wheat beers either)
