I purchased my first sack of 2 Row a few months ago from the LHBS and noticed right after I got it home that it was about 40% grain husk. Being a newbie, it took me a while to realize my sack of grain wasn't up to scratch. It took numerous lower yield batches to figure it out. I eventually hauled it back to the store and they told me it must be an 'end of run' bag. Lucky for me they agreed to switch it out for another bag.
A word to the wise... check your bag before heading home with it. If they won't let you open the bag to check the contents, compare it with other sacks. A good one should be densely packed. My husk filled sack was visibly oversized and pillowy when compared with the good ones.
