I just did my Wee Heavy last weekend with roughly 15 lbs of grain and I had plenty of room. Based on the results of the calculator located at the above link, I should be fine up to a bit over 28 lbs. I'd obviously never use that much unless I was going to do a 10 gal batch, but good to know what my max is.
30 lbs of grain at a mash thickness of 1 qt/lb = 9.9 gallons.
