I am getting 82% at .035" on the BC
I have never used the BMW crush, but they get rave reviews from people that have changed NOTHING except that they started to order thier crushed malt from BMW as opposed to other stores.
FWIW, I know a couple LHBS owners, and they say that they dont make money on malt, but they do on hops, equipment, cleaners etc. So I dunno why any store would sell anyone a crappy crush, but they certainly do.
I used to get uncrushed kernels in my orders from a certain store.
